在sqrt{s} = 1.96 TeV的p-p-bar碰撞中寻找衰变为双光子的疏费米子希格斯玻色子

Search for a Fermiophobic Higgs Boson Decaying into Diphotons in p p-bar Collisions at sqrt{s} = 1.96 TeV

CDF Collaboration, T. Aaltonen

摘要:

利用CDF实验收集的sqrt{s} = 1.96 TeV的p-棒p碰撞的3.0 fb^{-1}积分亮度数据,对窄双光子质量共振进行了研究.在双光子质谱中没有观察到共振的证据,并且在共振态的横截面乘以分支分数上设置上限作为希格斯玻色子质量的函数。由此产生的限制排除了质量低于106 GeV的希格斯玻色子,在95%的贝叶斯可信度水平(C.L.)对于一个费米恐惧的基准模型。

英文摘要:

A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb^{-1} of integrated luminosity from p-bar p collisions at sqrt{s} = 1.96 TeV collected by the CDF experiment. No evidence of a resonance in the diphoton mass spectrum is observed, and upper limits are set on the cross section times branching fraction of the resonant state as a function of Higgs boson mass. The resulting limits exclude Higgs bosons with masses below 106 GeV at a 95% Bayesian credibility level (C.L.) for one fermiophobic benchmark model.
