The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature.
The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft)
This synchrotron is designed to collide opposing particle beams of either protons at an energy of 7 teraelectronvolts (7 TeV or 1.12 microjoules) per nucleon, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus (2.76 TeV per nucleon). The term hadron refers to particles composed of quarks
The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics, including testing for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry.
