A search for a narrow Higgs boson resonance in the diphoton mass spectrum is presented based on data corresponding to 7.0 fb{-1} of integrated luminosity from pp collisions at sqrt[s]=1.96 TeV collected by the CDF experiment. No evidence of such a resonance is observed, and upper limits are set on the cross section times branching ratio of the resonant state as a function of Higgs boson mass. The limits are interpreted in the context of the standard model and one fermiophobic benchmark model where the data exclude fermiophobic Higgs bosons with masses below 114 GeV/c{2} at a 95% Bayesian credibility level.
基于 CDF 实验在 sqrt[s]=1.96 TeV 的 pp 碰撞中采集的 7.0 fb{−1}积分亮度数据，对光子对质量谱中的窄 Higgs 玻色子共振进行了搜索。未观察到这种共振的证据，并对共振态的横截面积与分支比作为 Higgs 玻色子质量的函数进行了上限设置。在标准模型和一个费米子惰性基准模型的背景下对限制进行了解释，在这个基准模型中，数据在 95%贝叶斯置信度水平下排除了质量低于 114 GeV/c{2}的费米子惰性 Higgs 玻色子。
