Reconciling threshold and subthreshold expansions for pion-nucleon scattering
D. Siemens, J. Ruiz de Elvira, E. Epelbaum +4
Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion-nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects e…

Elastic pion-nucleon scattering in chiral perturbation theory: A fresh look
D. Siemens, V. Bernard, E. Epelbaum +3
Elastic pion-nucleon scattering is analyzed in the framework of chiral perturbation theory up to fourth order within the heavy-baryon expansion and a covariant approach based on an…
