Different vertex parameterizations and propagators for the Δ contribution in π-photoproduction
We evaluate the total cross section for the π-photoproduction process and analyze the behavior of the Δ(1232) resonance contribution when the photon energy is increased from threshold up to 0.7 GeV. Within this energy range we compare two different parameterizations for the γNΔ vertex: the normal pa...
