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).

It spans the French-Swiss border, and was so expensive to build that over a dozen governmental and non-governmental bodies had to chip in to get it done.TLAS is probably the most famous of the LHCâs experiments â this is where CERN collected most of the data that eventually confirmed the existence of the Higgs boson. It stands for A Toroidal LHC ApparatuS (bit of a stretch for that last Sâ¦) and it gapes with a diameter of more than 80 feet!
