摘要：
The straightforward application of dimensional regularization and minimal subtraction leads to problems with the power counting in a manifestly Lorentz-invariant formulation of baryon chiral perturbation theory. These complications can be avoided by using alternative renormalization schemes, such as infrared regularization and the extended on-mass-shell scheme. Some recent applications of these formalisms are discussed, including the chiral expansion of the nucleon mass and nucleon form factors. The extension of these methods to include additional degrees of freedom is also addressed.
