在sqrt(s)= 7 TeV的pp碰撞中H到ZZ到2l 2nu通道中搜索标准模型希格斯玻色子

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

The CMS Collaboration

摘要:

在质心能量为7 TeV的pp碰撞中,在H → ZZ → 2l ~ 2nu(l = e或μ)衰变通道中寻找标准模型希格斯玻色子.这些数据是在大型强子对撞机上用CMS探测器收集的,对应的积分亮度为4.6飞秒。没有观察到显著的过量超过背景预期,并且在希格斯玻色子产生截面上设定了上限。质量在270-440 GeV范围内的标准模型希格斯玻色子的存在被排除在95%的置信水平之外。

英文摘要:

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.
