Baryon Chiral Perturbation Theory A.D. 1994

Abstract

In these lectures, the status of baryon chiral perturbation theory is reviewed. Particular emphasis is put on the two--flavor sector and the physics related to electromagnetic probes. I discuss in some detail the structure of the effective Lagrangian at next--to--leading order, the meaning of low--energy theorems in Compton scattering and pion photoproduction and confront the chiral predictions with the existing data. Some remaining problems and challenges are outlined.
