A composite boson is a a bound state of Fermions such that the combination gives a boson. Some examples are: Cooper pairs, mesons, Superfluid helium, Bose–Einstein condensates, Atomic bosons, and many other composite quantum states like Fermionic condensates. These composite particle states have a symmetric wave function upon exchange of any pair of particles. The wave function is given by the permanent of single particle states for the non interacting case.
