报告题目:A unique $\gamma_5$ prescription for the Standard Model in Dimensional Regularization

 

报告人:陈龙 研究员 (山东大学)

 

报告时间:2023109 上午10:00

 

报告地点:理8118学术报告厅

 

报告内容:

Calculating correctly the high-order perturbative corrections to quantities involving an axial-current operator in dimensional regularization (DR) is non-trivial due to the well-known $\gamma_5$ issue in D dimensions. In this talk we will review a few practical mainstream prescriptions that have been successfully applied in many high-order perturbative calculations, and discuss their advantages and disadvantages both from the technical side and the conceptual side. In the end, we propose a unique prescription for treating $\gamma_5$ in the Standard Model in DR.
