Model of the Strong Couplings

An attempt is made to construct a crude field theory of hyperons and $K$ particles, which are assumed to have spin ½ and spin 0, respectively. The parity of $\Lambda$ is defined to be plus. Some preliminary experimental evidence is adduced in support of parity plus for $\Sigma$. It is further argued that $\Lambda$ and $\Sigma$ are coupled to $\pi$ with roughly the same coupling constant as in the $\pi -N$ case, while the coupling of $K$ to baryons is weaker.
