the large Hadron collider

The Large Hadron Collider (LHC)


The large hadron Collider is the World's largest and the highest-energy particle accelerator, and it's one of the great engineering milestones of human begins. It was first built by the European organization for nuclear research (CERN) from 1998 to 2008,
with the aim of allowing physicist to test the predictions of different theories of particle physics and high energy physics,and particularly prove or disprove the existence of the theorised Higgs-Boson and of the large family of new particles predicted by supersymmetric theories. The LHC contains six detectors each designed for specific kinds of exploration. It is expected to address some of the still unsolved questions of physics, advancing human understanding of physics laws.

This LHC was built in collaboration with over 10000 engineers and scientists from over 100 countries, as Well as hundreds of universities and laboratories. This LHC lies in a tunnel 27 km in circumference, as deep as 175 m beneath the Franco-Swiss border near Geneva, Switzerland. 




The term 'hadron' refers here to the composite particles composed of quarks held together by an strong force (the intermolecular forces between particles of atom) . best known hadron are protons and neutrons (also include mesons such as pion and kaon ).

And a collider refers here to a type of accelerator with directed beams of elementary particles . in particle physics collider used as a research tool ; they accelerate particles to very high kinetic energies and let them impact other particles. Analysis of the byproducts of these collisions gives scientists a good evidence of the structure of subatomic world and the laws of nature governing it. Many of these byproducts are produced only produced by high energy collisions, and they decay after short period of time.
