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 a particle accelerator built near Geneva, Switzerland. Buried approximately 50 to 175 meters underground, the Large Hadron Collider resides inside a circular tunnel roughly 27 kilometers in circumference, running along the border between Switzerland and France.ince the Large Hadron Collider will be having collisions of such high energy, the hope is that it will release exotic particles which are normally not observed.
