Measuring the Higgs Boson Self-Coupling with ATLAS

乔尔将使用ATLAS探测器在大型强子对撞机上搜索希格斯玻色子对的产生。这种搜索对强子对撞机上的希格斯场自相互作用特别敏感。乔尔将专注于用b喷注和强子衰变的轻子来研究双希格斯粒子产生的最终状态。与其他选择相比，这些最终状态具有较高的横截面，但由于高背景，众所周知，很难观察到这些最终状态。该项目的一个关键组成部分将是改进ATLAS触发系统，用于最终状态下的多个强子物体的签名。

Joel will perform searches for Higgs Boson pair production at the LHC with the ATLAS detector. Such searches are uniquely sensitive to the Higgs field self-interaction at hadron colliders. Joel will focus on final states of di-Higgs production with b-jets and hadronically-decaying tau-leptons. These final states have high cross sections compared to alternatives but are notoriously difficult to observe due to high backgrounds. A key component of this project will be improving the ATLAS trigger system for signatures with multiple hadronic objects in the final state.
