论文摘要
已经进行了许多尝试,以观察希格斯玻色子对光子的腐烂和无形的无质量深色光子。为了使LHC可能可以观察到这种衰减,必须存在标准模型和深色光子之间交流的新介质。在这封信中,我们研究了来自HIGGS信号强度,倾斜参数,电子和单位性的电动偶极矩的此类介体的界限。我们发现,希格斯玻色子与光子和深色光子的分支比率限制为远小于当前撞机搜索的敏感性,因此要求重新考虑当前的实验努力。
Many attempts have been made to observe the decay of the Higgs boson to a photon and an invisible massless dark photon. For this decay to be potentially observable at the LHC, new mediators that communicate between the Standard Model and the dark photon must exist. In this Letter, we study bounds on such mediators coming from the Higgs signal strengths, oblique parameters, electric dipole moment of the electron and unitarity. We find that the branching ratio of the Higgs boson to a photon and a dark photon is constrained to be far smaller than the sensitivity of current collider searches, thus calling for a reconsideration of current experimental efforts.
