Meson–baryon scattering in resummed baryon chiral perturbation theory using time-ordered perturbation theory

Abstract Integral equations for meson–baryon scattering amplitudes are obtained by utilizing time-ordered perturbation theory for a manifestly Lorentz-invariant formulation of baryon chiral perturbation theory. Effective potentials are defined as sums of two-particle irreducible contributions of tim...
