Abstract

We discuss the decays of high-spin natural-parity resonances lying on a leading Regge trajectory. We do this by studying the reaction VP→PP in a dual resonance model with trajectories which are nondegenerate in the resonance region. This allows for SU(4)-symmetry breaking in meson decay rates. Owing to the factorization property of Regge slopes and to the equal-spacing rule, we find rates which depend only on an overall normalization (and the low sa trajectory slope αρ′). Agreement with data is good.
