摘要:

对希格斯玻色子性质的研究为测试标准模型之外的物理效应提供了令人信服的视角,并对大型强子对撞机计划和未来的对撞机产生了深远的影响。准确测定希格斯玻色子的性质可以为我们提供一个独特的希格斯扇区的精确图像,设定严格的边界,并预测新物理模型参数值的范围。在本文中,我们讨论的限制超对称性,可以通过确定的希格斯玻色子玻色子的质量和耦合。我们量化这些限制,通过使用扫描的19参数空间的所谓的现象学最小超对称标准模型。可以排除希格斯粒子测量的扫描点的分数进行了研究,在LHC运行2中获得的耦合测量精度和预期的HL-LHC程序和$e^+e^-$对撞机,并与那些来自丢失的横向能量搜索在LHC和暗物质实验。

英文摘要:

The study of the Higgs boson properties offers compelling perspectives for testing the effects of physics beyond the Standard Model and has deep implications for the LHC program and future colliders. Accurate determinations of the Higgs boson properties can provide us with a distinctively precise picture of the Higgs sector, set tight bounds, and predict ranges for the values of new physics model parameters. In this paper, we discuss the constraints on supersymmetry that can be derived by a determination of the Higgs boson mass and couplings. We quantify these constraints by using scans of the 19-parameter space of the so-called phenomenological minimal supersymmetric Standard Model. The fraction of scan points that can be excluded by the Higgs measurements is studied for the coupling measurement accuracies obtained in LHC Run 2 and expected for the HL-LHC program and $e^+e^-$ colliders and contrasted with those derived from missing transverse energy searches at the LHC and from dark matter experiments.
