Power counting in relativistic baryon chiral perturbation theory
arXiv:hep-ph/0308177
Abstract
We consider a renormalization scheme for relativistic baryon chiral perturbation theory which provides a simple and consistent power counting for renormalized diagrams. As an application we discuss the chiral expansion of the nucleon mass.
