Medical Definition of MESON

: any of a group of unstable elementary particles that are subject to nuclear forces and have masses much greater than that of the electron
me·son·ic \me-ˈzän-ik, mē-, -ˈsän-\ adjective


noun    (Concise Encyclopedia)

Any member of a family of subatomic particles composed of a quark and an antiquark (see antimatter). Mesons are sensitive to the strong force, have integral spin, and vary widely in mass. Though unstable, many mesons last a few billionths of a second, long enough to be observed with particle detectors. They are readily produced in the collisions of high-energy subatomic particles (e.g., in cosmic rays).
