Improved description of the $\pi N$-scattering phenomenology in covariant baryon chiral perturbation theory

J. M. Alarcón, J. Martin Camalich, J. A. Oller

We present a novel analysis of the $\pi N$ scattering amplitude in covariant baryon chiral perturbation theory up to $\mathcal{O}(p^3)$ within the extended-on-mass-shell renormalization…
