摘要

顶夸克的产生可以用不同的方式探索标准模型(SM)之外的物理。有效场论(EFT)框架允许以独立于模型的方式寻找超越SM (BSM)的效应。CMS实验是EFT测量的先驱，朝着以最可能的全球方式充分利用数据潜力的方向发展。在CMS中，对口味变化中性电流(FCNC)和异常顶夸克相互作用的搜索也在进行，这是对EFT方法的补充。本次演讲回顾了目前在顶级领域对FCNC搜索的限制，以及EFT解释。

FCNC and EFT interpretations in top quark events in CMS

Top quark production can probe physics beyond the standard model (SM) in different ways. The Effective Field Theory (EFT) framework allows searching for beyond the SM (BSM) effects in a model independent way. CMS experiment is pioneering EFT measurements that move towards using full potential of the data in the most global way possible. Searches for flavour-changing neutral currents (FCNC) and anomalous top quark interactions are also being pursued in CMS which are complementary to the EFT approach. This talk reviews the current limits on FCNC searches in the top sector, and EFT interpretations.
