PARITY-NONCONSERVATION AND THE SPINS OF THE STRANGE PARTICLES
Journal Article

· Progr. Theoret. Phys. (Kyoto)
Taking into account possible parity-nonconservation in weak interactions, the decay angular distributions of strange particles produced by pion-nucleon collisions are re-examined. It is shown that, when the paritynonconservation effect is actually observed in the decay angular distribution of the hyperon, its spin value can be determined less ambiguously than in the case of the parity-conservation. Especially, in this case, it is possible in principle to decide completely whether the spin is 1/2 or not. The effect of the parity-nonconservation can appear also in the K/sub mu /sup 2/ - and K/sub pi /sup 3/ -modes of decay, unless the spin of K is zero. The possibility of determining the spin value of the K-meson is considernd. In this case the conclusion is not so decisive as the case of the hyperon. (auth)
