在sqrt(s)=7 TeV的pp碰撞中H到ZZ到ll τ τ衰变通道中寻找标准模型希格斯玻色子

Search for the standard model Higgs boson in the H to ZZ to ll tau tau decay channel in pp collisions at sqrt(s)=7 TeV

The CMS Collaboration

摘要:

本文报道了在质子-质子碰撞中寻找标准模型希格斯玻色子的衰变模式H到ZZ到τ +轻子对,轻子可以是电子也可以是μ子,能量为7 TeV,对应于LHC CMS探测器收集的积分亮度为4.7毫微微粒子。没有证据表明与背景预期存在重大偏差。对于质量范围190 < m(H)< 600 GeV的标准模型希格斯玻色子产生截面和衰变分支分数的乘积,将比预测值大4至12倍的上限设定为95%置信水平。

英文摘要:

A search is reported for the standard model Higgs boson in the decay mode H to ZZ to tau plus lepton pairs, where the leptons are either electrons or muons, in proton-proton collisions at sqrt(s)=7 TeV, corresponding to an integrated luminosity of 4.7 inverse femtobarn collected with the CMS detector at the LHC. No evidence is found for a significant deviation from the background expectation. An upper limit four to twelve times larger than the predicted value is set at 95% confidence level for the product of the standard model Higgs boson production cross section and decay branching fraction in the mass range 190 < m(H) < 600 GeV.
