Status of three-flavor baryon chiral perturbation theory [chapter]

U.-G. Meißner
Chiral Dynamics: Theory and Experiment  
I review the present status of three flavor baryon chiral perturbation theory in the heavy fermion formalism. It is argued that precise calculations have to include all terms quadratic in the quark masses. As examples, I consider the chiral expansion of the octet baryon masses, the baryon magnetic moments and kaon photoproduction off nucleons.
