Probing the top-Higgs coupling with the ATLAS detector

希格斯玻色子和顶夸克之间的耦合是标准模型中大的顶夸克质量的原因。这种耦合可以通过标准模型之外的物理学来修改，这可能解释诸如暗物质的性质和质量起源等悬而未决的问题。在这个项目中，学生将使用大型强子对撞机上的ATLAS探测器对顶-希格斯耦合进行新的测量。这些测量可能包括四顶末态的第一微分截面测量，或与顶夸克相关的非常高的横向动量希格斯玻色子的测量，这两者都对顶-希格斯耦合敏感。

The coupling between the Higgs boson and the top quark is responsible for the large top quark mass in the Standard Model. The coupling can be modified by physics beyond the Standard Model that may explain outstanding questions such as the nature of dark matter and the origin of mass. In this project the student will make new measurements sensitive to the top-Higgs coupling using the ATLAS detector at the Large Hadron Collider. The measurements may include first differential cross-section measurements of the four-top final state or measurements of very high transverse momentum Higgs bosons produced in association with top quarks, both of which are sensitive to the top-Higgs coupling.
