论文摘要
标准模型Higgs玻色子的标准信号可以耗尽的两种简单方法是：它与费米子和仪表玻色子的耦合可以被通用因子抑制，并且其部分分支分数可以将其排入无形的最终状态。大量理论可以通过标准模型下的单身式的其他标量玻色子来施加这两个耗竭因素，即使轻度，但与希格斯玻色子混合在一起。我们对耗尽的希格斯玻色子的当前状态进行了全面的调查，并讨论了检测两种耗竭因子的存在的未来前景。我们还调查了额外混合标量的通用案例的约束状态和未来检测前景，这通常会导致希格斯玻色子的这些耗尽因素。例如，在许多情况下，对Higgs玻色子的精确研究比搜索额外的标量状态更强大，因为鉴于下一代实验的板岩即将到来。
Two simple ways by which the standard signals of the Standard Model Higgs boson can be depleted are: its couplings to fermions and gauge bosons can be suppressed by a universal factor, and part of its branching fraction can be drained into invisible final states. A large class of theories can impose one or both of these depletion factors, even if mild, by way of additional scalar bosons that are singlets under the Standard Model but mix with the Higgs boson. We perform a comprehensive survey of the present status of the depleted Higgs boson, and discuss future prospects for detecting the presence of either depletion factor. We also survey the constraints status and future detection prospects for the generic case of extra mixed-in scalars which generically lead to these depletion factors for the Higgs boson. We find, for example, that precision study of the Higgs boson in many cases is more powerful than searches for the extra scalar states, given the slate of next-generation experiments that are on the horizon.
