A search for neutral minimal supersymmetric standard model (MSSM) Higgs bosons in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 36 pb(-1) recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs. No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space.
介绍了在 LHC 上进行的质心能量为 7 TeV 的 pp 碰撞中对中性最小 supersymmetric 标准模型(MSSM)希格斯玻色子的搜索。结果基于 CMS 实验记录的对应于 36 pb-1 的积分亮度的数据集。该搜索使用希格斯玻色子衰变为 tau 对。在 tau 对不变质量谱中没有观察到过剩。作为赝标量希格斯玻色子质量的函数,对 tau 对的希格斯玻色子产生截面乘以分支比的上限,在 MSSM 参数空间中产生了严格的新约束。
