论文摘要
我们探索新物理模型，这些模型可能会导致Higgs衰减速率至$Zγ$的大型增强（100％或更多），同时仍然与其他测量值保持一致。我们表明，这是在具有一个附加多重组的简单模型中不可能的，并且在诸如MSSM和折叠的SUSY等动机模型中也是不可能的。我们确实找到了具有多个多重型的模型，这些模型在可能的增强中，但它们需要破坏性的干扰效应。我们还表明，Higgs衰减至四个瘦素的运动学测量值可能对此类模型敏感。最后，我们探讨了四个轻子测量对超对称模型的敏感性，并发现虽然高光度LHC很难进行测量，但使用未来的高能量Hadron对撞机可能是可能的。
We explore models of new physics that can give rise to large (100% or more) enhancements to the rate of Higgs decay to $Zγ$ while still being consistent with other measurements. We show that this is impossible in simple models with one additional multiplet and also in well motivated models such as the MSSM and folded SUSY. We do find models with several multiplets that carry electroweak charge where such an enhancement is possible, but they require destructive interference effects. We also show that kinematic measurements in Higgs decay to four leptons can be sensitive to such models. Finally we explore the sensitivity of four lepton measurements to supersymmetric models and find that while the measurement is difficult with the high luminosity LHC, it may be possible with a future high energy hadron collider.
