Regularization of Non-Linear Spinor Field Models by Discrete Symmetries

TL;DR

This paper extends a regularization technique for non-linear spinor field models to higher-order theories and non-scalar interactions, utilizing discrete symmetries related to C, P, and T transformations.

Contribution

It generalizes a previous regularization method to more complex models involving higher-order terms and non-scalar interactions, linked with fundamental discrete symmetries.

Findings

Successfully extended regularization to fourth order theories

Incorporated non-scalar interactions into the regularization framework

Connected discrete symmetries with C, P, T transformations in the regularization process

Abstract

We generalize a regularization method of Stumpf 1984 in the case of non-linear spinor field models to fourth order theories and to non-scalar interactions. The involved discrete symmetries can be connected with C,P,T transformations.
