We investigate the interplay between crossed channel final state interactions and the constraints from two particle unitarity for the reactions Psi to V pi pi and VK Kbar, where V is either omega or phi. Using a model where the parameters are largely constrained by other sources, we find that, although small, crossed channel final state interaction can influence the amplitudes considerably, in special areas of phase space. These results cast doubt on the inapplicability of unitarity constraints on production amplitudes as recently claimed in the literature. |
