Phenomenological description of the reaction K-p→anti K*0(890)(π-p) using a dual fermion model

Using the Neveu-Schwarz-Ramond model as a starting point, attempts have been made to construct a phenomenological dual amplitude for the reaction K-p→anti K*0(890)(π-p). The amplitude contains trajectories of both natural and unnatural spin-parity in the exchange channel as well as Nsub(α), Nsub(γ) and Δ trajectories in the production channel. Furthermore, it has the correct Regge behaviour in both meson and fermion channels. Reasonable agreement between the predictions and the data with respect to differential cross sections and density matrix elements has been found. (Auth.)
