| dc.description.abstract | 有關暗光子的理論主要是出自於早期天文物理觀測的結果與 現有理論不符合，這些觀測結果指出新物理的存在。為了解 釋觀測結果，理論學家延伸自標準模型 U(1)群，在 Hidden Sector 中建立了一個新的假設性的 U(1)群。暗光子為此假設 性的 U(1)群的介子。歐洲核子 物理研究所的大強子對撞機為 目前世界上對撞能量最高且高亮度的質子質子對撞機，因此 擁有龐大的潛能來尋找 GeV 質量尺度的暗光子。本篇論文利 用質子-質子質心能量√s = 13 TeV 的對撞產生希格斯粒子， 暗光子則藉由希格斯粒子的稀有衰變來產生，並且通過暗光 子的渺子衰變頻道來尋找新的渺子-渺子對不變質量共振來尋 找暗光子，此研究使用 2016 年全年度 CMS 所蒐集的資料進

| dc.description.abstract | The hypothesis of Dark Photon(ZD) is motivated by a number of astrophysi- cal observational anomalies which indicate the new physics beyond Standard Model(SM) is existing in our world. The Hidden Sector contains a hypothetical U (1)D gauge group is introduced by extension of the SM. The ZD is a theoretical particle which does not play a role as Dark Matter(DM) itself but play a role as gauge mediator of hypothetical hidden U(1)D gauge group. With the advent of the Large Hadron Collider(LHC), a powerful machine with unprecedented high central-of-mass energies and high luminosities gives the potential to probe the GeV scale ZD. The searches of ZD from exotic Higgs decays and decaying into a muon pair in pp collision with √s = 13 TeV is ongoing by looking for new dilepton invariant mass in sub-GeV scale. This analysis using full 2016 data recorded by CMS detector in integrated luminosity 35.9 fb?1. | en_US |
