We present a search for the standard model Higgs boson and a fermiophobic Higgs boson in the diphoton final states based on 8.2 fb(-1) of pp collisions at sqrt[s]=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. No excess of data above background predictions is observed and upper limits at the 95% C.L. on the cross section multiplied by the branching fraction are set which are the most restrictive to date. A fermiophobic Higgs boson with a mass below 112.9 GeV is excluded at the 95% C.L.
我们展示了在费米实验室 Tevatron 对撞机上的 D0 探测器收集的 8.2 fb-1 的 sqrt[s]=1.96 TeV pp 碰撞数据中,在双光子末态中对标准模型希格斯玻色子和无费米子性希格斯玻色子的搜索结果。没有观察到超出背景预测的数据,并且在 95%置信度水平下对截面乘以分支比的上限是迄今为止最严格的。质量低于 112.9 GeV 的无费米子性希格斯玻色子在 95%置信度水平下被排除。
