Since the fifties, hadron reactions have been studied at higher and higher energies as technology has improved. The internal and kinetic energies of colliding particles form new particles via the strong interaction.
LHC (the Large Hadron Collider) at CERN will be used to collide beams of protons traveling in opposite directions at the highest energies yet achieved. This can result in the production of a variety of particles with more possibilities because of the high energy. Mesons and hadrons such as the p (pi) meson, K, S (sigma) and neutrons can be produced. There is a possibility that particles never seen before will be created, and theories will be verified or disproved.
