meson

mes·on  (mzn, ms-, mzn, -sn)

n.

Any of a family of subatomic particles that participate in strong interactions, are composed of a quark and an antiquark, and have masses generally intermediate between leptons and baryons. See Table at subatomic particle.

me·sonic (m-znk, -sn, m-) adj.

meson [ˈmiːzɒn]

n

(Physics / 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

[from meso- + -on]

mesonic , mesic adj

meson  (mzn, ms-, mzn, -sn)

Any of a family of subatomic particles that are composed of a quark and an antiquark. Their masses are generally intermediate between leptons and baryons, and they can have positive, negative, or neutral charge. Mesons form a subclass of hadrons and include the kaon, pion and J/psi particles. Mesons were originally believed to be the particles that mediated the strong nuclear force, but it has since been shown that the gluon mediates this force. See Table at subatomic particle.
