'''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 force|strong nuclear force]] (as mediated by [[gluon]]s). They are responsible for mediating the strong force between [[protons]] and [[neutron]]s in the nuclei of [[atom]]s, holding the nuclei together. | '''Mesons''' are composite particles that are known as [[bosons]] on account of their integer spin, otherwise known as angular momentum.
