论文摘要

在本文中,我们介绍了完整的一环匹配条件,直到标准模型有效字段理论的尺寸六算子,通过整合两个标量leptoquarks $ s_ {1} $和$ s_ {3} $。这允许以一环准确性对该模型的低能限制进行现象学研究,这将是后续工作的重点。此外,它为正在开发的一环匹配的功能和计算方法提供了丰富的比较。作为推论结果,我们得出了一组完整的二维运算符,该尺寸是由零件集成的独立于集成的,而不是在动作方程式下(称为Green的基础),以及从该集合到华沙基础的完整还原公式。

In this paper we present the complete one-loop matching conditions, up to dimension-six operators of the Standard Model effective field theory, resulting by integrating out the two scalar leptoquarks $S_{1}$ and $S_{3}$. This allows a phenomenological study of low-energy constraints on this model at one-loop accuracy, which will be the focus of a subsequent work. Furthermore, it provides a rich comparison for functional and computational methods for one-loop matching, that are being developed. As a corollary result, we derive a complete set of dimension-six operators independent under integration by parts, but not under equations of motions, called Green's basis, as well as the complete reduction formulae from this set to the Warsaw basis.
