Off-shell model for threshold pionic eta production on a nucleon and for etaN scattering

Journal Article · · Phys. Rev. Lett.; (United States)
;
An off-shell isobar model for ..pi..N..--> pi..N, ..pi..N..-->..etaN, and etaN..-->..etaN t matrices is presented. The ..pi..N, etaN, and ..pi delta..+(..pi pi..N) channels are treated in a coupled-channel formalism. We are able to determine various vertex functions of the model by using only ..pi..N (complex) phase shifts in S/sub 11/, P/sub 11/, D/sub 13/, and P/sub 33/ partial waves. The model gives good predictions for ..pi../sup -/p..-->..etan cross sections. It also predicts an attractive S-wave etaN interaction.
