MSSM中的手性增强校正

Chirally enhanced corrections in the MSSM

Andreas Crivellin

摘要:

在一般的MSSM中,手征增强的修正(汤川耦合)是由胶子-夸克、电荷-费米子和中性粒子-费米子环引起的,由于它们的手征增强,它们可以在数值上与树能级的贡献竞争,甚至占主导地位。在这篇文章中,我回顾了这些修正的重申,所有订单在微扰理论的基础上,最近的工作所做的合作与拉尔斯·赫塞和雅努什·罗西克(arXiv:1103.4272)。

英文摘要:

In the general MSSM, chirally-enhanced corrections (to Yukawa couplings) are induced by gluino-squark, chargino-sfermion and neutralino-sfermion loops and can numerically compete with, or even dominate over, tree-level contributions, due to their chiral enhancement. In this article I review the resummation of these corrections to all orders in pertubation theory based on recent work done in collaboration with Lars Hofer and Janusz Rosiek (arXiv:1103.4272).
