Abstract
The supercovergent, double spin-flip, sum rule for ρ-π scattering is saturated att=0, together with its first derivative att=0. The particles corresponding to the two lowest multiplets of the rest symmetryU6⊗U6⊗O3 are used in the saturation. Where possible, experimental values for masses and coupling constants are inserted. A bound is obtained for the ratio ofd-wave tos-wave coupling for the A1→ρπ decay. The effect of higher resonances is considered briefly, and the consistency of the saturation with the related current algebra sum rules is discussed.
