Particles produced in collisions in the Large Hadron Collider(LHC) are tiny and extremely short-lived. Because they almost immediately decay into further particles, it is impossible for physicists to directly “see” them. Instead, they look at the properties of the final particles, such as their charge, mass, spin and … See more
