Abstract

We list the conspiracy relations for reactions of type Π+N→V+N and Π+N→V+Δ, emphasizing that there are relations connecting states with opposite parity at t=0 even when all four masses are unequal. We show in detail that if the relations are satisfied by vanishing of the couplings of individual trajectories at t=0, all helicity-flip amplitudes are suppressed at forward angles; whereas if the relations are satisfied by conspiracy among various trajectories, the flip-flip amplitudes which conserve angular momentum in forward scattering can contribute with full strength.
