摘要：Calculating correctly the high perturbative order corrections to quantities involving the chirality matrix $\gamma_5$ in dimensional regularization (DR) is non-trivial due to the well-known $\gamma_5$ issue. In this talk we will review a few practical prescriptions successfully applied in the past, and discuss their advantages and disadvantages both from the conceptual and technical side. In the end of the talk, we present a new procedure "g5anchor" to anchor $\gamma_5$ in the definition of a cyclic Dirac trace with $\gamma_5$ in dimensionally-regularized Feynman diagrams for the Standard Model.
