    Abstract: 本篇論文旨在尋找於質子–質子對撞下產生的雙希格斯粒子,分別衰變至一對光子及一對底夸克。
    本分析使用了於2016年由大強子對撞機(LHC)產生的質子–質子對撞,總能量為√s=13 TeV,並由緊湊緲子線圈(CMS)所記錄,總亮度達到35.9/fb。
    本研究沒有觀察到顯著的訊號事件,並提供了實驗上對理論參數以及新粒子重量的限制區間。;The search is presented for the production of a pair of Higgs bosons in the final state with two photons and two b quarks by full 2016 data, which corresponds to an integrated luminosity of 35.9/fb recorded by the CMS detector.
    Both resonant and non-resonant processes are investigated for the Standard Model (SM) and the Beyond the Standard Model (BSM) theories.
    The non-resonant production helps us to understand the Higgs field structure in the SM and other possible effects from BSMs.
    The resonant production is predicted by many BSMs. In this thesis, the hypothesis with the spin-0 and spin-2 new heavy particles which can decay into two Higgs bosons is searched and compared with the prediction from the warped extra dimension theory.
    The b-jet energy regression specifically developed for this analysis are employed to improve the sensitivity about 10%.
    The observed results agree with the standard model prediction, and the limits on the exclusion of the BSM productions are also set.
