Europe's Large Hadron Collider Restarts

Large Hadron Collider (LHC) built by the scientists of European Organization for Nuclear Research (CERN in French), has increased the energy of beams to 1.28 tera electron volts (TeV) from 0.450 TeV. This surpassed the 0.98 TeV record set by America's Tevatron collider in 2001.

The LHC, in a 17-mile circular tunnel, under the Franco-Swiss border, is expected to create conditions just before the creation of the universe (or just after the Big Bang).

Scientists plan to increase the energies in the two proton beams at a gradual pace. In 2010, the accelerator is expected to reach 7 TeV. According to scientists, the collider should be able to hit the 14 TeV target, in the end of the year, allowing them to make beams of protons ram into each other at almost the speed of light. With this, the accelerator is expected to unlock some of the universe's mysteries, such as the 'God particle' or Higgs boson.

The first collider was built in early 20th century, to study objects smaller than protons and neutrons. Inside the collider, beams are sent crashing into those coming in the opposite direction, to observe what comes out.

As the size of the colliders increased, physicists were able to discover objects like quarks, that were held together by gluons. This led to the Standard Model of particle physics, which revealed how the universe looked at the subatomic level.

However, the theory has not been able to explain why particles have mass and their distinctive properties. Scientists believe that Higgs is the particle that gives matter its mass. Higgs is an unstable particle and when created artificially will exist for a very short time. Scientists say that, it may be fourth or fifth generation daughter particle which is stable enough to be observed.

According to scientists, initially collisions of low-energy will be done for the purpose of calibration. The first significant physics results are expected in the first quarter of next year.
