Relativistic chiral representation of the scattering amplitude I: The Goldberger-Treiman relation
J. M. Alarcon, J. Martin Camalich, J. A. Oller
In this work we study the scattering process within the Baryon Chiral Perturbation Theory framework in the covariant scheme of Extended-On-Mass-Shell (EOMS). We compare the de…
The chiral representation of the scattering amplitude and the pion-nucleon sigma term
J. M. Alarcon, J. Martin Camalich, J. A. Oller
We present a novel analysis of the scattering amplitude in Lorentz covariant baryon chiral perturbation theory renormalized in the extended-on-mass-shell scheme. This amplitud…
Relativistic chiral representation of the πN scattering amplitude
J. M. Alarcón, J. Martín Camalich, J. A. Oller +1
We have analyzed pion-nucleon scattering using the manifestly relativistic covariant frameworks of Infrared Regularization (IR) and Extended-On-Mass-Shell (EOMS) up to O(q^3) in th…
πN scattering in relativistic baryon chiral perturbation theory revisited
J. M. Alarcon, J. Martin Camalich, J. A. Oller +1
We have analyzed pion-nucleon scattering using the manifestly relativistic covariant framework of Infrared Regularization up to {\cal O}(q^3) in the chiral expansion, where q is a…
