noun Abbr. K
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.
Origin: ka, pronunciation of the letter K + -on1.
kaon - Science Definition
Any of three unstable mesons, one having charge +1 and a mass of 966 electron masses, and two being electrically neutral, with a mass 974 electron masses. Their half-life is approximately 10-8 seconds, and they decay through the weak force. Their decay patterns suggest that CP invariance may be violated. Also called K-meson, K particle. See Table at subatomic particle.
