A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3).
The Large Hadron Collider (LHC) is the world's biggest and most powerful particle accelerator. It was built by the European Organization for Nuclear Research (CERN).It is a giant circular tunnel built underground. The tunnel is 17 miles (27 kilometers) long, and between 50 and 175 meters below the ground. It lies beneath the border of Switzerland and France.t was built by the European Organization for Nuclear Research (CERN). It is a giant circular tunnel built underground.
