顶夸克变味相互作用的整体研究

A global approach to top-quark flavor-changing interactions

Gauthier Durieux, Fabio Maltoni, Cen Zhang

摘要:

我们采用完全规范不变的有效场论方法来参数化顶夸克变味中性流相互作用。它允许对实验约束(或测量)进行全局解释,并系统地处理高阶量子校正。我们讨论了最近的一些结果在下一个领先的阶精度QCD和执行,在该顺序,第一个全球性的分析的一个子集的有效算子系数的可用的实验限制。我们鼓励实验合作采用这种方法,并通过使用他们可以获得的所有信息来扩展分析。

英文摘要:

We adopt a fully gauge-invariant effective-field-theory approach for parametrizing top-quark flavor-changing-neutral-current interactions. It allows for a global interpretation of experimental constraints (or measurements) and the systematic treatment of higher-order quantum corrections. We discuss some recent results obtained at next-to-leading-order accuracy in QCD and perform, at that order, a first global analysis of a subset of the available experimental limits in terms of effective operator coefficients. We encourage experimental collaborations to adopt this approach and extend the analysis by using all information they have prime access to.
