从自然新物理学角度解读LHC Higgs结果

Interpreting LHC Higgs Results from Natural New Physics Perspective

Dean Carmi, Adam Falkowski, Eric Kuflik, Tomer Volansky

摘要:

我们分析了2011年LHC希格斯数据的背景下,简化的新物理模型解决自然性问题。这些模型预计将包含与希格斯玻色子有相当大耦合的新粒子,这可以很容易地修改希格斯产生的截面和分支分数。我们专注于搜索希格斯4轻子和希格斯双光子通道,在后者的情况下,包括矢量玻色子融合生产模式。结合现有的ATLAS和CMS数据在这些渠道,我们推导出一个有效的低能量理论的希格斯玻色子的约束。然后,我们将几个简化的场景映射到有效的理论,捕获许多自然的新物理模型,如超对称和小希格斯,并提取相应的参数空间上的约束。我们表明,简单的模型,其中一个费米子或一个标量合作伙伴是负责稳定的希格斯势已经限制在一个非平凡的方式由大型强子对撞机希格斯数据。

英文摘要:

We analyze the 2011 LHC Higgs data in the context of simplified new physics models addressing the naturalness problem. These models are expected to contain new particles with sizable couplings to the Higgs boson, which can easily modify the Higgs production cross sections and branching fractions. We focus on searches in the Higgs to 4 leptons and Higgs to diphoton channels, in the latter case including the vector boson fusion production mode. Combining the available ATLAS and CMS data in these channels, we derive constraints on an effective low-energy theory of the Higgs boson. We then map several simplified scenarios to the effective theory, capturing numerous natural new physics models such as supersymmetry and Little Higgs, and extract the constraints on the corresponding parameter space. We show that simple models where one fermionic or one scalar partner is responsible for stabilizing the Higgs potential are already constrained in a non-trivial way by LHC Higgs data.
