Participatory Notes Issue in January 2008

Participatory notes issue in January 2008On October 16, 2007, SEBI (Securities & Exchange Board of India) proposed curbs on participatory notes which accounted for roughly 50% of FII investment in 2007. SEBI was not happy with P-notes because it was not possible to know who owned the underlying securities, and hedge funds acting through P-notes might therefore cause volatility in the Indian markets.

However the proposals of SEBI were not clear and this led to a knee-jerk crash when the markets opened on the following day (October 17, 2007). Within a minute of opening trade, the Sensex crashed by 1744 points or about 9% of its value - the biggest intra-day fall in Indian stock markets in absolute terms till then. This led to automatic suspension of trade for 1 hour. Finance Minister P. Chidambaram issued clarifications, in the meantime, that the government was not against FIIs and was not immediately banning PNs. After the market opened at 10:55 AM, the index staged a comeback and ended the day at 18715.82, down 336.04 from the last day's close.

This was, however not the end of the volatility. The next day (October 18, 2007), the Sensex tumbled by 717.43 points — 3.83 per cent — to 17998.39. The slide continued the next day when the Sensex fell 438.41 points to settle at 17559.98 at the end of the week, after touching the lowest level of that week at 17226.18 during the day.

After detailed clarifications from the SEBI chief M. Damodaran regarding the new rules, the market made a 879-point gain on October 23, thus signalling the end of the PN crisis.In anuary 2008In the third week of January 2008, the Sensex experienced huge falls along with other markets around the world. On 21 January 2008, the Sensex saw its highest ever loss of 1,408 points at the end of the session. The Sensex recovered to close at 17,605.40 after it tumbled to the day's low of 16,963.96, on high volatility as investors panicked following weak global cues amid fears of a recession in the US.

The next day, the BSE Sensex index went into a free fall. The index hit the lower circuit breaker in barely a minute after the markets opened at 10 AM. Trading was suspended for an hour. On reopening at 10.55 AM IST, the market saw its biggest intra-day fall when it hit a low of 15,332, down 2,273 points. However, after reassurance from the Finance Minister of India, the market bounced back to close at 16,730 with a loss of 875 points.

Over the course of two days, the BSE Sensex in India dropped from 19,013 on Monday morning to 16,730 by Tuesday evening or a two day fall of 13.9%.

BSE Sensex

The Bombay Stock ExchangeThe BSE Sensex or Bombay Stock Exchange Sensitive Index is a value-weighted index composed of 30 stocks with the base April 1979 = 100. It consists of the 30 largest and most actively traded stocks, representative of various sectors, on the Bombay Stock Exchange. These companies account for around one-fifth of the market capitalization of the BSE.
The base value of the sensex is 100 on April 1, 1979, and the base year of BSE-SENSEX is 1978-79.
At irregular intervals, the Bombay Stock Exchange (BSE) authorities review and modify its composition to make sure it reflects current market conditions.

The index has increased by over ten times from June 1990 to the present. Using information from April 1979 onwards, the long-run rate of return on the BSE Sensex works out to be 18.6% per annum, which translates to roughly 9% per annum after compensating for inflation.

Forex Scam

A forex scam is any trading scheme used to defraud individual traders by convincing them that they can expect to gain a high profit by trading in the foreign exchange market. Currency trading "has become the fraud du jour," according to Michael Dunn of the U.S. Commodity Futures Trading Commission.But "the market has long been plagued by swindlers preying on the gullible," according to the New York Times."The average individual foreign-exchange-trading victim loses about $15,000, according to CFTC records" according to The Wall Street Journal.The North American Securities Administrators Association says that "off-exchange forex trading by retail investors is at best extremely risky, and at worst, outright fraud."
“In a typical case, investors may be promised tens of thousands of dollars in profits in just a few weeks or months, with an initial investment of only $5,000. Often, the investor’s money is never actually placed in the market through a legitimate dealer, but simply diverted – stolen – for the personal benefit of the con artists.

The forex market is a zero-sum game meaning that whatever one trader gains, another loses, except that brokerage commissions and other transaction costs are subtracted from the results of all traders, technically making forex a "negative-sum" game.

These scams might include churning of customer accounts for the purpose of generating commissions, selling software that is supposed to guide the customer to large profits,improperly managed "managed accounts",false advertising,Ponzi schemes and outright fraud. It also refers to any retail forex broker who indicates that trading foreign exchange is a low risk, high profit investment.

The U.S. Commodity Futures Trading Commission (CFTC), which loosely regulates the foreign exchange market in the United States, has noted an increase in the amount of unscrupulous activity in the non-bank foreign exchange industry.

An official of the National Futures Association was quoted as saying, "Retail forex trading has increased dramatically over the past few years. Unfortunately, the amount of forex fraud has also increased dramatically..." Between 2001 and 2006 the U.S. Commodity Futures Trading Commission has prosecuted more than 80 cases involving the defrauding of more than 23,000 customers who lost $350 million. From 2001 to 2007, about 26,000 people lost $460 million in forex frauds.CNN quoted Godfried De Vidts, President of the Financial Markets Association, a European body, as saying, "Banks have a duty to protect their customers and they should make sure customers understand what they are doing. Now if people go online, on non-bank portals, how is this control being done?"

Large Hadron Collider (LHC)

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator complex, intended to collide opposing beams of protons charged with approximately 7 TeVs of energy. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. It is theorized the collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass.

The LHC was built by the European Organization for Nuclear Research (CERN), and lies underneath the Franco-Swiss border near Geneva, Switzerland. It is funded by and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories. The LHC is now operational, and in the process of being prepared for first collisions. The first beam was circulated through the collider on 10 September 2008 and the first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008.

Although a few individuals have questioned the safety of the planned experiments in the media and through the courts, the consensus in the scientific community is that there is no basis for any conceivable threat from the LHC particle collisions.

Technical Design
The LHC is the world's largest and highest-energy particle accelerator. The collider is contained in a circular tunnel with a circumference of 27 kilometres (17 mi) at a depth ranging from 50 to 175 metres underground. The 3.8 metre (150 inches) diameter, concrete-lined tunnel, constructed between 1983 and 1988, was formerly used to house the LEP, an electron-positron collider. It crosses the border between Switzerland and France at four points, although most of it is in France. Surface buildings hold ancillary equipment such as compressors, ventilation equipment, control electronics and refrigeration plants.

The collider tunnel contains two adjacent beam pipes, each containing a proton beam (a proton is one type of hadron). The two beams travel in opposite directions around the ring. Some 1,232 bending magnets keep the beams on their circular path, while an additional 392 focusing magnets are used to keep the beams focused, in order to maximize the chances of interaction between the particles in the four intersection points, where the two beams will cross. In total, over 1,600 superconducting magnets are installed, with most weighing over 27 tonnes. Approximately 96 tonnes of liquid helium is needed to keep the magnets at their operating temperature of 1.9 K, making the LHC the largest cryogenic facility in the world at liquid helium temperature.

Once or twice a day, as the protons are accelerated from 450 GeV to 7 TeV, the field of the superconducting bending magnets will be increased from 0.54 T to 8.3 T.

The protons will each have an energy of 7 TeV, giving a total collision energy of 14 TeV. At this energy the protons have a gamma factor of about 7,500 and move at about 99.999999% of light speed. It will take less than 90 microseconds for a proton to travel once around the main ring (a speed of about 11,000 revolutions per second). Rather than continuous beams, the protons will be bunched together, into 2,808 bunches, so that interactions between the two beams will take place at discrete intervals never shorter than 25 ns apart. When the collider is first commissioned, it will be operated with fewer bunches, to give a bunch crossing interval of 75 ns. The number of bunches will later be increased to give a final bunch crossing interval of 25 ns.

Prior to being injected into the main accelerator, the particles are prepared by a series of systems that successively increase their energy. The first system is the linear accelerator Linac 2 generating 50 MeV protons, which feeds the Proton Synchrotron Booster (PSB). There the protons are accelerated to 1.4 GeV and injected into the Proton Synchrotron (PS), where they are accelerated to 26 GeV. Finally the Super Proton Synchrotron (SPS) is used to increase their energy to 450 GeV before they are at last injected (over a period of 20 minutes) into the main ring, where proton bunches are accumulated, accelerated (over a period of 20 minutes) to their peak 7 TeV energy, and finally stored for many hours (10 to 24) while collisions occur at the four intersection points.

The LHC will also be used to collide lead (Pb) nuclei with a collision energy of 1,150 TeV. The Pb ions will be first accelerated by the linear accelerator Linac 3, and the Low-Energy Injector Ring (LEIR) will be used as an ion storage and cooler unit. The ions then will be further accelerated by the Proton Synchrotron (PS) and Super Proton Synchrotron (SPS) before being injected into LHC ring, where they will reach an energy of 2.76 TeV per nucleon.

Six detectors are being constructed at the LHC, located underground in large caverns excavated at the LHC's intersection points. Two of them, the ATLAS experiment and the Compact Muon Solenoid (CMS), are large, general purpose particle detectors. A Large Ion Collider Experiment (ALICE) is designed to study the properties of quark-gluon plasma from the debris of heavy-ion collisions. The other three, LHCb, TOTEM, and LHCf, are smaller and more specialized.

Detectors

BBC quotes about LHC CMS detectors:

“ ATLAS - one of two so-called general purpose detectors. Atlas will be used to look for signs of new physics, including the origins of mass and extra dimensions

CMS - the second general purpose detector will, like ATLAS, hunt for the Higgs boson and look for clues to the nature of dark matter

ALICE - will study a "liquid" form of matter called quark-gluon plasma that existed shortly after the Big Bang

LHCb - Equal amounts of matter and anti-matter were created in the Big Bang. LHCb will try to investigate what happened to the "missing" anti-matter”

Purpose
When activated, it is theorized that the collider will produce the elusive Higgs boson. The verification of the existence of the Higgs boson would be a significant step in the search for a Grand Unified Theory, which seeks to unify three of the four known fundamental forces: electromagnetism, the strong nuclear force and the weak nuclear force, leaving out only gravity. The Higgs boson may also help to explain why gravitation is so weak compared with the other three forces. In addition to the Higgs boson, other theorized particles, models and states might be produced, and for some searches are planned, including supersymmetric particles, compositeness (technicolor), extra dimensions, strangelets, micro black holes and magnetic monopoles.

Research

When in operation, about seven thousand scientists from eighty countries will have access to the LHC. Physicists hope to use the collider to test various grand unified theories and enhance their ability to answer the following questions:

* Is the popular Higgs mechanism for generating elementary particle masses in the Standard Model realised in nature? If so, how many Higgs bosons are there, and what are their masses?

* Will the more precise measurements of the masses of the quarks continue to be mutually consistent within the Standard Model?

* Do particles have supersymmetric ("SUSY") partners?

* Why are there apparent violations of the symmetry between matter and antimatter?

* Are there extra dimensions, as predicted by various models inspired by string theory, and can we "see" them?

* What is the nature of dark matter and dark energy?

* Why is gravity so many orders of magnitude weaker than the other three fundamental forces?

Renowned British astrophysicist Stephen Hawking has bet $100 the mega-experiment will not find the elusive particle seen as the holy grail of cosmic science. "I think it will be much more exciting if we don't find the Higgs. That will show something is wrong, and we need to think again. I have a bet of 100 dollars that we won't find the Higgs," said Prof Hawking. Hawking said the experiment could discover superpartners, particles that would be "supersymmetric partners" to particles already known about. "Their existence would be a key confirmation of string theory, and they could make up the mysterious dark matter that holds galaxies together," he said on the BBC. "Whatever the LHC finds, or fails to find, the results will tell us a lot about the structure of the universe," he said.

As an ion collider

The LHC physics program is mainly based on proton-proton collisions. However, shorter running periods, typically one month per year, with heavy-ion collisions are included in the programme. While lighter ions are considered as well, the baseline scheme deals with lead ions. This will allow an advancement in the experimental programme currently in progress at the Relativistic Heavy Ion Collider (RHIC).

Test timeline

September 2008

The first beam was circulated through the collider on the morning of 10 September 2008. CERN successfully fired the protons around the tunnel in stages, several kilometres at a time. The particles were fired in a clockwise direction into the accelerator and successfully steered around it at 10:28 am local time. The LHC successfully completed its first major test, for after a series of trial runs, two white dots flashed on a computer screen showing the protons traveled the full length of the Collider. CERN plans to send it counterclockwise, and eventually the two beams will be fired in opposite directions with the aim of smashing together protons to see how they are made. It took less than one hour to guide the stream of particles around its inaugural circuit.

October 2008

The first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008.

Proposed upgrade

After some years of running, any particle physics experiment typically begins to suffer from diminishing returns; each additional year of operation discovers less than the year before. The way around the diminishing returns is to upgrade the experiment, either in energy or in luminosity. A luminosity upgrade of the LHC, called the Super LHC, has been proposed, to be made after ten years of LHC operation. The optimal path for the LHC luminosity upgrade includes an increase in the beam current (i.e., the number of protons in the beams) and the modification of the two high luminosity interaction regions, ATLAS and CMS. To achieve these increases, the energy of the beams at the point that they are injected into the (Super) LHC should also be increased to 1 TeV. This will require an upgrade of the full pre-injector system, the needed changes in the Super Proton Synchrotron being the most expensive.

Cost

The total cost of the project is anticipated to be between €3.2 to €6.4 billion. The construction of LHC was approved in 1995 with a budget of 2.6 billion Swiss francs (€1.6 billion), with another 210 million francs (€140 million) towards the cost of the experiments. However, cost over-runs, estimated in a major review in 2001 at around 480 million francs (€300 million) for the accelerator, and 50 million francs (€30 million) for the experiments, along with a reduction in CERN's budget, pushed the completion date from 2005 to April 2007. 180 million francs (€120 million) of the cost increase have been due to the superconducting magnets. There were also engineering difficulties encountered while building the underground cavern for the Compact Muon Solenoid. In part this was due to faulty parts loaned to CERN by fellow laboratories Argonne National Laboratory or Fermilab.

Computing resources

The LHC Computing Grid is being constructed to handle the massive amounts of data produced by the Large Hadron Collider. It incorporates both private fibre optic cable links and existing high-speed portions of the public Internet, to get data from CERN to academic institutions around the world.

The distributed computing project LHC@home was started to support the construction and calibration of the LHC. The project uses the BOINC platform to simulate how particles will travel in the tunnel. With this information, the scientists will be able to determine how the magnets should be calibrated to gain the most stable "orbit" of the beams in the ring.

Safety issues

Safety of particle collisions

Main article: Safety of the Large Hadron Collider

Although some individuals, including some scientists, have questioned the safety of the planned experiments in the media and through the courts, the consensus in the scientific community is that there is no basis for any conceivable threat from the LHC particle collisions.

Operational safety

The size of the LHC constitutes an exceptional engineering challenge with unique operational issues on account of the huge energy stored in the magnets and the beams. While operating, the total energy stored in the magnets is 10 GJ and the total energy carried by the two beams reaches 724 MJ.

Loss of only one ten-millionth part (10−7) of the beam is sufficient to quench a superconducting magnet, while the beam dump must absorb an energy equivalent to that of a typical air-dropped bomb. These immense energies are even more impressive when one considers how little matter is carrying it. Under nominal operating conditions (2,808 bunches per beam, 1.15×1011 protons per bunch), the beam pipes contain 1.0×10-9 gram of hydrogen, which, in standard conditions for temperature and pressure, would fill the volume of one grain of fine sand.

Construction accidents and delays

On 25 October 2005, a technician was killed in the LHC tunnel when a crane load was accidentally dropped. On 27 March 2007 a cryogenic magnet support broke during a pressure test involving one of the LHC's inner triplet (focusing quadrupole) magnet assemblies, provided by Fermilab and KEK. No one was injured. Fermilab director Pier Oddone stated "In this case we are dumbfounded that we missed some very simple balance of forces". This fault had been present in the original design, and remained during four engineering reviews over the following years. Analysis revealed that its design, made as thin as possible for better insulation, was not strong enough to withstand the forces generated during pressure testing. Details are available in a statement from Fermilab, with which CERN is in agreement. Repairing the broken magnet and reinforcing the eight identical assemblies used by LHC delayed the startup date, then planned for November 2007, by several weeks.

In popular culture

The Large Hadron Collider has been featured in a number of novels, including Flashforward by Robert J. Sawyer, Black Hole by Angelo Paratico, and Decipher by Stel Pavlou, which described it in some detail. One of the most visible examples is Angels & Demons by Dan Brown, which involves dangerous antimatter created at the LHC used as a weapon against the Vatican. CERN published a "Fact or Fiction?" page discussing the accuracy of the book's portrayal of the LHC, CERN, and particle physics in general. The movie version of the book had footage filmed on-site at one of the experiments at the LHC; the director, Ron Howard, also met with CERN experts in an effort to make the science in the story more accurate. Katherine McAlpine, aka "alpinekat", a science writer working at CERN, wrote the lyrics for a personal rap video about the LHC called the "The Large Hadron Rap". The song was added to YouTube on 28 July 2008, and, as of 6 September, it had been viewed more than a million times.

BBC Radio 4 is broadcasting "Big Bang Day" on 10 September 2008 to coincide with the LHC being switched on. Included in this event will be a radio episode of the TV series Torchwood, with a plot surrounding the LHC, entitled Lost Souls.

On September 10, to commemorate the firing of the Large Hadron Collider, Google displayed a custom logo with a drawing of the LHC which linked to a web search for "Large Hadron Collider". It is a tradition for Google to change their logo to represent what they consider to be important or interesting events.

India betrayed! so say "No Deal"

The United States will not sell sensitive nuclear technologies to India and would immediately terminate nuclear trade if New Delhi conducted a nuclear test, the Bush administration told Congress in correspondence that has remained secret for nine months.

The correspondence, which also appears to contradict statements by Indian officials, was made public on 2 September, 2008 by Rep. Howard L. Berman (D-Calif.), chairman of the House Foreign Affairs Committee, just days before the 45-nation Nuclear Suppliers Group meets again in Vienna to consider exempting India from restrictions on nuclear trade as part of a landmark U.S.-India civil nuclear deal.

The NSG, which governs trade in reactors and uranium, poses a key hurdle for the U.S-India pact. The group operates by consensus, allowing even small nations to block or significantly amend any agreement. The United States has pressed the NSG to impose few conditions on India, even though it has tested nuclear weapons and has not signed the nuclear Non-Proliferation Treaty.

A significant group of nations balked at the proposal when the NSG first discussed it two weeks ago. Berman's release of the correspondence could make approval even more difficult because it demonstrates that U.S. conditions for nuclear trade with India are tougher than what the United States is requesting from the NSG on India's behalf.

About 20 nations offered more than 50 amendments to the U.S.-proposed draft text, focusing on terminating trade if India resumes testing and bans on the transfer of sensitive technologies.

The correspondence released by Berman is "going to reinforce the views of many states," said Daryl G. Kimball, executive director of the Arms Control Association, which opposes the U.S.-India agreement. "There is no reason why this should not be an NSG-wide policy."

The correspondence concerned 45 highly technical questions that members of Congress posed about the deal. In 2006, Congress passed a law, known as the Hyde Act, to provisionally accept the agreement. But some lawmakers raised concerns about whether a separate implementing agreement negotiated by the administration papered over critical details to assuage Indian concerns. The questions were addressed in a 26-page letter sent to Berman's predecessor, the late Rep. Tom Lantos (D-Calif.), on Jan. 16.

The answers were considered so sensitive, particularly because debate over the agreement in India could have toppled the government of Prime Minister Manmohan Singh, that the State Department requested they remain secret even though they were not classified.

Lynne Weil, a spokeswoman for Berman, said he made the answers public yesterday because, if NSG approval is granted, the U.S-India deal soon would be submitted to Congress for final approval and "he wants to assure that Congress has the relevant information."

In India, Singh and his aides have insisted that the deal would not constrain the country's right to nuclear tests and would provide an uninterrupted supply of fuel to India's nuclear reactors. In August 2007, Singh told Parliament, "The agreement does not in any way affect India's right to undertake future nuclear tests, if it is necessary."

The State Department's letter to Lantos gives a different story. It says the United States would help India deal only with "disruptions in supply to India that may result through no fault of its own," such as a trade war or market disruptions. "The fuel supply assurances are not, however, meant to insulate India against the consequences of a nuclear explosive test or a violation of nonproliferation commitments," the letter said.

The letter makes clear that terminating cooperation could be immediate and was within U.S. discretion, and that the supply assurances made by the United States are not legally binding but simply a commitment made by President Bush.

The letter also stated that the "U.S. government will not assist India in the design, construction or operation of sensitive nuclear technologies," even though the Hyde Act allowed transfers of such technology under certain circumstances. The U.S. government had no plans to seek to amend the deal to allow sensitive transfers, the letter said.

The administration is eager for NSG approval this week because there is a narrow window for final congressional action before lawmakers adjourn this month, although many of them say the prospects for quick action remain dim.

Reflecting the importance of the U.S.-India deal to Bush's foreign policy legacy, Secretary of State Condoleezza Rice is dispatching two top officials -- William J. Burns, undersecretary of state for political affairs, and John Rood, acting undersecretary of state for arms control and international security -- to the NSG session.

Concerns about the deal have been raised by a group of mostly smaller states, led by Ireland and New Zealand. But this week China also publicly urged caution, saying in a foreign ministry statement that the NSG must "strike a balance between nuclear nonproliferation and peaceful use of energy."
