 Bose-Einstein statistics

Start by looking at: Maxwell-Boltzmann vs Bose-Einstein vs Fermi-Dirac statistics.

Bose-Einstein statistics is a set of statistical rules that describe the behavior of bosons, which are particles that obey Bose-Einstein statistics. Bosons are a category of elementary particles that have integer spin (0, 1, 2, etc.) and include particles such as photons, gluons, and the Higgs boson.
