CP Violation in Neutral Meson Oscillations - Neutral Kaon Mixing - Mixing
... of CP with opposite eigenvalues K1 has CP = +1, and K2 has CP = -1 Since the two-pion final state also has CP = +1, only the K1 can decay this way ... The K2 must decay into three pions ... a little larger than the sum of the masses of three pions, this decay proceeds very slowly, about 600 times slower than the decay of K1 into two pions ...
