Stefan Scherer (Mainz):


Baryon chiral perturbation theory



We will give a short introduction to the one-nucleon sector of chiral perturbation theory and will address the issue of a consistent power counting and renormalization. We will discuss the infrared regularization and the extended on-mass-shell scheme. Both allow for the inclusion of further degrees of freedom beyond pions and nucleons and the application to higher-loop calculations. As applications we consider the chiral expansion of the nucleon mass at two-loop order and the inclusion of vector and axial-vector mesons in the calculation of nucleon form factors.
