High-spin meson decays in the dual resonance model with nondegenerate Regge trajectories
1978
Physical Review D, Particles and fields
%e discuss the decays of high-spin natural-parity resonances lying on a leading Regge trajectory. %e 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 s p trajectory slope o. '). Agreement with data is good.
