1* The neutral Kaons K⁰_s and K⁰_L represent symmetric and antisymmetric mixtures of the quark combinations down-antistrange and antidown-strange. Decay times in this range indicate decay by the weak interaction.

What do kaons decay into a level?

CONSERVATION OF ANGULAR MOMENTUM

Figure 11.24. The kaon (K⁺) is an unstable particle that spontaneously decays into a pion pair (π⁺ and π°). Here the pions emerge from the decay in opposite directions along the same line. This decay is observed.

What particles do kaons decay into?

K mesons or kaons are unstable and can decay in a number of ways. In one important but very rare decay, a positive kaon – a bound state of an up quark and a strange antiquark — decays into a positive pion plus a neutrino and an antineutrino.
