The differential and integrated cross section data for the hypercharge exchange reactions πp→K°(1420)Λ, K - p→f°Λ and K - p→f′Λ at 4 GeV/c are fitted by using as imple Regge pole model with phenorncnological residue functions. It is assumed that each of the two non-degenerate K* and K** trajectories, exchanged in this reaction, is coupled only to one of the two independent helicity amplitudes.
Abstract
The differential and integrated cross section data for the hypercharge exchange reactions πp→K°(1420)Λ, K - p→f°Λ and K - p→f′Λ at 4 GeV/c are fitted by using as imple Regge pole model with phenorncnological residue functions. It is assumed that each of the two non-degenerate K* and K** trajectories, exchanged in this reaction, is coupled only to one of the two independent helicity amplitudes.
