mes·on

 (mĕz′ŏn′, mĕs′-, mē′zŏn′, -sŏn′, mā′-)
n.
Any of a class of subatomic particles that are both hadrons and bosons, are composed of a quark and an antiquark, participate in strong interactions, and have masses generally intermediate between those of leptons and baryons.

meson

(ˈmiːzɒn)
n
(Atomic Physics) any of a group of elementary particles, such as a pion or kaon, that usually has a rest mass between those of an electron and a proton, and an integral spin. They are responsible for the force between nucleons in the atomic nucleus. Former name: mesotron See also muon
