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 largest and most powerful particle collider, the largest, most complex experimental facility ever built, and the largest single machine in the world.he proton-proton collision is the primary operation method, but the LHC has also collided protons with lead nuclei for two months in 2013 and used leadâlead collisions for about one month each in 2010, 2011, and 2013 for other investigations.
