Abstract:We adopt a novel formalism for the low-energy analysis of the γp → K + πΣ photoproduction reaction to calculate the πΣ invariant mass distributions in the Λ(1405) resonance region. The approach adheres to constraints arising from unitarity, gauge invariance and chiral perturbation theory, and is used without adjusting any model parameters. It is found that the meson-baryon rescattering in the final state has a major impact on the magnitude and structure of the generated spectra that are compared with the exper… Show more
