Multiple particle systems in quantum mechanics are described by wavefunctions with many arguments. Such wavefunctions must also obey exchange symmetry or antisymmetry in order to describe the particles as indistinguishable. There are two ways to achieve this symmetry/antisymmetry, referred to in the particle physics context as to fermions and bosons, where fermions obey the Pauli exclusion principle while bosons do not.
