Measuring the Higgs Boson Self-Coupling with ATLAS

乔尔将在大型强子对撞机上用ATLAS探测器搜索希格斯玻色子对的产生。这样的搜索是唯一敏感的希格斯场自相互作用在强子对撞机。乔尔将专注于双希格斯粒子与b喷流和强子衰变的τ轻子的最终状态。这些最终状态与其他状态相比具有高截面，但由于高背景而难以观察。该项目的一个关键组成部分将是改进ATLAS触发系统的签名与多个强子物体在最终状态。

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.
