  • n. Any of a subgroup of unstable mesons that consist of an electrically charged form with a mass 966 times that of an electron and a neutral form with a mass 974 times that of an electron, produced as a result of a high-energy particle collision. Also called K-meson. See Table at subatomic particle.
