在四轻子实验学家的理论中加入伪观测量
Adding Pseudo-Observables to the Four-Lepton Experimentalist's Toolbox
摘要:
新发现的希格斯玻色子玻色子通过中间矢量玻色子衰变为四轻子的“黄金”通道,对于确定希格斯玻色子玻色子的性质和寻找新的物理效应具有重要意义。不同的方法存在参数化相关的希格斯耦合在这个通道中,在这里,我们涉及到使用伪观测值的方法的基础上指定最一般的振幅或拉格朗日项的$HVV$相互作用。我们还提供了几种新的情况下,在这个通道的敏感性预测,说明使用伪观测,并分析了运动分布和(比率)率在这样的$H\to4\ell$研究中的作用。
英文摘要:
The "golden" channel, in which the newly-discovered Higgs boson decays to four leptons by means of intermediate vector bosons, is important for determining the properties of the Higgs boson and for searching for subtle new physics effects. Different approaches exist for parametrizing the relevant Higgs couplings in this channel; here we relate the use of pseudo-observables to methods based on specifying the most general amplitude or Lagrangian terms for the $HVV$ interactions. We also provide projections for sensitivity in this channel in several novel scenarios, illustrating the use of pseudo-observables, and analyze the role of kinematic distributions and (ratios of) rates in such $H\to4\ell$ studies.
