Radiative pion photoproduction in covariant chiral perturbation theory

NUCLEAR REACTIONS ¹H(γ, pπ⁰γ), (polarized γ, pπ⁰γ), (γ, nπ⁺γ), (polarized γ, nπ⁺γ), E<200 MeV; calculated differential σ(E), convergence of the small-scale expansion and sensitivity to magnetic moment of Δ⁺, double differential σ(E, θ), polarization asymmetries. Covariant chiral perturbation theory with explicitΔ(1232) degrees of freedom, including contributions up to next-to-next-to-leading order, with errors from the truncation of the small-scale expansion estimated using Bayesian approach. Comparison with experimental data from MAMI-Mainz facility.
