Experiments at Record Power are Launched on LHC


06/03/2015

Researchers have begun to receive scientific data at the Large Hadron Collider (LHC) with record energy collisions of protons - 13 teraelectronvolt. This is about twice the previous value, which led to the discovery of the Higgs boson. This is stated on the website of the European Organization for Nuclear Research (CERN).

Beams of protons are accelerated to near-light speed in the LHC’s 27-kilometer tunnel, to achieve such power. Today, each particle beams moving in opposite directions, comprises six packets, each of which has around 100 billion protons. Gradually, the number of packets will be increased to 2808 pieces in each beam what will provide the origin of one billion collisions per second.

The collider was stopped by 14 February 2013. After its two-year preventive maintenance and modernization, a trial run was held on April 5 and the first collision with the energy of each beam 6.5 teraelectronvolt occured 21 May. Now, the LHC is working full-power continuously, which allows scientists to obtain new data.

Higher energy collisions and enhancing their frequency increase the chance of showing previously unregistered particles in the reactions. After the discovery of the Higgs boson in 2012, all elementary particles in the so-called Standard Model, has been open. Now scientists hope to find signs of new physics - elements of dark matter and supersymmetric partners of known particles.

Supersymmetry is a very powerful tool in the hands of the theorists to combine that was still unable to be united, namely to link the building blocks of matter fermions (particles with half-integer spin) and vectors of interacting bosons (particles with integer spin). According to the supersymmetric theory - they are one and the same, only seen from different angles. And most importantly, every known particle according to this supermirror theory must comply with the supersymmetric partner. However, the space with such angles has three dimensions like ours, but whether ten, or eleven, and people have no chance to see these additional measurements. The main disappointment of the first experiments in the LHC consist in the fact that no trace of supersymmetry were detected.

Scientists hope - and this is perhaps one of the most important expectations associated with the Super Collider’s Run 2 - now at a qualitatively new level of energy collisions they could get a chance to detect signs of supersymmetric particles. Also, there is hope for other discoveries that could be a shocking surprise.

LHC - the world's largest accelerator installation. It is located in CERN on the border of France and Switzerland. In 2012, experts of the organization reported the discovery of a particle with the properties of the Higgs boson.
