'''Mesons''' are composite particles that are known as [[bosons]] on account of their integer spin, otherwise known as angular momentum. Mesons are composed of a quark-antiquark pair, held by the strong nuclear force (as mediated by [[gluon]]s). | '''Mesons''' are composite particles that are known as [[bosons]] on account of their integer spin, otherwise known as angular momentum.
