Renormalization of the meson-baryon SU(3) Lagrangian in chiral perturbation theory to order q3
Guido Müller
Abstract
We perform the complete regularization of all Green functions with a single incoming and outgoing baryon to order q3 in the low energy expansion for the SU(3) meson-baryon system in chiral perturbation theory. The divergences can be extracted in a chiral invariant manner by making use of the heat kernel representation of the propagators in d-dimensional Euclidean space.
