Experimental Studies of the Higgs Mechanism in the Standard Model and Beyond

该奖项为使用欧洲核子研究中心大型强子对撞机的ATLAS探测器记录的数据进行研究提供资金。所进行的分析将在实验室环境中以最高的能量和最短的距离推进我们对宇宙的理解。我们将测量希格斯玻色子的产生和衰变特性，根据我们最好的理论模型，希格斯玻色子负责宇宙中的所有质量，并在宇宙的最终稳定性中发挥关键作用。该小组还将利用这些数据来寻找与希格斯玻色子反应相关的新物理证据，这些证据目前并未包括在公认的理论中。这项工作为本科生和研究生提供了参与前沿科学研究和仪器开发的机会。这个项目支持的学生和博士后，通过他们自己的技术工作和研究，以及他们与工程师和技术人员的工作，为他们在学术界、工业和其他需要技术技能的领域的职业研究做准备。这项工作将使用与标准模型反应pp→H→BB、pp→HH→BBττ和pp→H→μμ相关的最终状态的大型强子对撞机Run 3数据进行。这项拟议的工作将寻找反应pp→H→AA→BBμμ，以及与轻子、中微子和双喷流终态的反应。这些搜索可能会产生长期寻求的超越标准模型物理的发现。这些通道中的最后一个将测量与希格斯相互作用相关的矢量玻色子散射过程，这是在标准模型中建立统一性所必需的。这项工作还将对目前的探测器进行探测器操作，并为跟踪系统和液体氩热量计系统进行高光度的升级。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award provides funding for research using data recorded by the ATLAS detector at the CERN Large Hadron Collider. The analyses carried out will advance our understanding of the universe at the highest energies, and therefore shortest distances, ever explored in a laboratory setting. Production and decay properties of the Higgs Boson will be measured, which, according to our best theoretical models, is responsible for all mass in the universe and which plays a crucial role in the ultimate stability of the universe. The group will also use the data to search for evidence of new physics associated with Higgs Boson reactions which are not currently included in accepted theories. This work gives undergraduate and graduate students an opportunity to participate in leading edge scientific research and instrumentation development. The students and postdocs to be supported by this project, through their own technical work and research and their work with engineers and technicians, prepares them for research in careers in academia, industry and other areas which require technical skills.This work will be performed using LHC Run 3 data in final states associated with the standard model reactions pp→H→bb, pp→HH→bbττ and pp→H→μμ. The proposed effort will search for the reaction pp → H → aa → bbμμ and also reactions with lepton, neutrino and dijet final states. These searches could yield long sought discoveries of Beyond the Standard Model physics. The last of these channels will measure vector boson scattering processes associated with Higgs interactions which are required to establish unitarity in the standard model. The work will also carry out detector operations of the current detector and upgrades for high luminosity for the tracking system and liquid Argon calorimeter system.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
