Abstract:	本篇論文研究了希格斯玻色子衰變為真實光子和虛光子的搜尋。研究也考慮了虛光子轉換成兩個μ介子的內部轉換。分析是根據大型強子對撞機上的 CMS 實驗在整個 Run-2 期間從質心能量為 13 TeV 的質子-質子對撞中收集到的數據進行的，對應於 137.1 fb^{-1} 的總亮度。與標準模型預測值相比，H-> γγ->μμγ 的分支比的預期上限被設定為1.09，標準模型希格斯玻色子的預期顯著性為 1.83σ。;A search for a Higgs boson decaying to a real and a virtual photon is studied. The internal conversion of a virtual photon into two muons is considered. The analysis is performed on data collected by the CMS experiment at the LHC from proton-proton collisions with a center-of-mass energy of 13 TeV during the full Run-2 period, corresponding to an integrated luminosity of 137.1 fb^{-1}. An expected upper limit was set on the ratio of the branching fraction of H->γγ->μμγ with respect to the Standard Model prediction to be 1.09, with an expected significance of 1.83σ for the Standard Model Higgs boson.
