寻找q rt(s)= 7和8时pp碰撞中衰变到μ + μ-的中性MSSM希格斯玻色子TeV

Search for neutral MSSM Higgs bosons decaying to mu+ mu- in pp collisions at sqrt(s) = 7 and 8 TeV

CMS Collaboration

摘要:

本文研究了在最小超对称标准模型(MSSM)中预测的μ + μ衰变通道的中性希格斯玻色子玻色子。分析使用CMS实验收集的数据在大型强子对撞机在质子-质子碰撞在质心能量为7和8 TeV,相应的积分亮度为5.1和19.3毫微微电子能垒,分别。这种搜索对通过胶子融合过程或与bb夸克对相关产生的希格斯玻色子玻色子很敏感。在mu+ mu-质谱中未观察到统计学显著过量。结果在几种基准场景的框架中进行解释,并且数据用于将MSSM参数tan(beta)的上限设置为赝标A玻色子质量的函数,范围为115至300 GeV。给出了胶子熔合和b夸克关联产生的截面与分支分数乘积的模型无关的上限。这是迄今为止在该渠道获得的最严格限制。

英文摘要:

A search for neutral Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) for mu+ mu- decay channels is presented. The analysis uses data collected by the CMS experiment at the LHC in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.3 inverse femtobarns, respectively. The search is sensitive to Higgs bosons produced through the gluon fusion process or in association with a bb quark pair. No statistically significant excess is observed in the mu+ mu- mass spectrum. Results are interpreted in the framework of several benchmark scenarios, and the data are used to set an upper limit on the MSSM parameter tan(beta) as a function of the mass of the pseudoscalar A boson in the range from 115 to 300 GeV. Model independent upper limits are given for the product of the cross section and branching fraction for gluon fusion and b quark associated production. They are the most stringent limits obtained to date in this channel.
