Abstract

The

π Λ Σ

coupling constant is determined by testing the sum rule which follows from the hypothesis of asymptotic conservation of

s

-channel helicity, and from the hypothesis that the

P^{'}

Regge trajectory decouples from the

A^{+}

amplitude in

π Σ

and

π Λ

diffraction scattering.
