Abstract:	對 H → Zγ → bbγ 與 Z 玻色子初步調查而以得呈現出有所相關性。這項分析是以 CMS detector 在√s = 13 TeV 所蒐集的資料作為基準，並符合 35.9 fb^{−1} 的積分亮度。H 玻色子與 Z 玻色子相關性是由電子與緲子其一的電荷相反輕子重新被組成。另一方面來說，希格斯玻色子是從Zγ最終產出的bbγ所重組而成。此分析以兩個 b-tagged 噴流被分成電子與緲子通道。在信賴水準95%，一個預期排除極限9.681 × 10^4到 4.138 × 10^4乘以電子通道中的標準模型值，而 4.081 × 10^4到 1.836 × 10^4 乘以在緲子通道中的標準模型值，而 3.863 × 10^4 到 1.669 × 10^4在兩者通道組合中。全部介於 120 GeV 到 130 GeV 的質量範圍就可獲得。;A preliminary search for H→Zγ→bbγ produced in association with a Z boson is presented. The analysis is based on the data collected in 2016 with the CMS detector at a center-of-mass energy √s = 13 TeV, corresponding to an integrated luminosity of 35.9 fb^{-1}. The Z boson produced in association with the Higgs boson is reconstructed from a pair of oppositely-charged leptons, either from electrons or muons. On the other hand, the Higgs boson is reconstructed from the Zγ in final states of b¯bγ. The analysis is separated into electron and muon channels with two b-tagged jets. An expected exclusion limit at 95% confidence level of 9.681x10^4 to 4.138x10^4 times the Standard Model value in the electron channel, 4.081x10^4 to 1.836x10^4 times the Standard Model value in the muon channel, and 3.863x10^4 to 1.669x10^4 in the combination of both channels have been obtained in the 120 GeV to 130 GeV mass range.
