Renormalization of the three flavor Lagrangian in heavy baryon chiral perturbation theory

Abstract

The complete renormalization of the generating functional for Green functions of quark currents between one--baryon states in three flavor heavy baryon chiral perturbation theory is performed to order q^3. As an example, we study the kaon loop induced divergences in neutral pion photoproduction off protons.
