/ ˈmi zɒn, ‐sɒn, ˈmɛz ɒn, ˈmɛs‐ /

noun

Physics. any hadron, or strongly interacting particle, other than a baryon. Mesons are bosons, having spins of 0, 1, 2, …, and, unlike baryons, do not obey a conservation law.

Compare quark model.

An elementary particle in the atomic nucleus.

Scientific definitions for meson

meson

[ mĕz′ŏn′, mĕs′-, mē′zŏn′, -sŏn′ ]

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.
