0 Dynamical model for Pion − Nucleon Bremsstrahlung

Abstract

A dynamical model based on effective Lagrangians is proposed to describe the bremsstrahlung reaction πN → πNγ at low energies. The ∆(1232) degrees of freedom are incorporated in a way consistent with both, electromagnetic gauge invariance and invariance under contact transformations. The model also includes the initial and final state rescattering of hadrons via a T-matrix with off-shell effects. The πNγ differential cross sections are calculated using three different T-matrix models and the results are compared with the soft photon approximation, and with experimental data. The aim of this analysis is to test the off-shell behavior of the different T-matrices under consideration. PACS numbers: 25.80.Ek, 13.60.-n, 13.75.-r
