They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin. Fermions have half-integer …

All particles have a corresponding anti-particle that is identical in many ways but opposite in others; for example, the mass and spin are the same but the charge is opposite.

This is a list of particles in particle physics, including currently known and hypothetical elementary particles, as well as the composite particles that can be built up from them.
