Hypercharge exchange reactions in quasieikonal model

Application of the quasieikonal model to the hypercharge exchange reactions π+p → K+Σ+, K-p → π-Σ+, π-p →Ksup(0)Σsup(0), anti Ksup(0)p → π+Σsup(0) is considered. Using the SU(3) symmetry ratios the amplitudes of Ksup(*) and Ksup(**) poles are related with amplitudes of rho and A2 poles obtained from the π-p → πsup(0)n and π-p → etan reactions. I n this case only the coupling constants of the SU(3) symmetry for vector and tensor poles have served as free parameters
