kaon

ka·on  (kn)

n. 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.

kaon [ˈkeɪɒn]

n

(Physics / General Physics) a meson that has a positive or negative charge and a rest mass of about 966 electron masses, or no charge and a rest mass of 974 electron masses Also called K-meson

[ka representing the letter k + (mes)on]

kaon  (kn)

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.
