Abstract:

A fit to high energy charged pion photoproduction in the relatively direction is performed on the basis of Regge pole model, where the existence of the pion conspirator is assumed to explain the sharp forward peak. New experimental data on the asymmetry in the cross sections between two states of the polarization of the initial proton normal to the plane of scattering are taken account of, in addition to the other available data up to the present. Good fits are obtained with the inclusion of the strong fixed pole effect for the ρ residue function at the wrong signature nonsense point αρ(t)=0. It also becomes clear that the ρ and A2 trajectories play very important role in the region 0.3<√-t<0.7. Furthermore the difficulty of pion conspiracy in connection with the reaction π+p→ρ0Δ++ is discussed.
