寻找sqrt(s)= 7 TeV pp碰撞中全轻子末态衰变为W对的标准模型希格斯玻色子

Search for the standard model Higgs boson decaying to a W pair in the fully leptonic final state in pp collisions at sqrt(s) = 7 TeV

CMS Collaboration

摘要:

本文报道了在sqrt(s)= 7 TeV pp碰撞中衰变到W+W-的标准模型希格斯玻色子的研究。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。W+W-的候选者被选择在事件中有两个带电轻子和大的失踪横能量。没有显着的事件超过标准模型的背景预期观察,并得出上限的希格斯玻色子生产相对于标准模型希格斯期望。在95%的置信水平下,在129-270 GeV的质量范围内排除了标准模型希格斯玻色子。

英文摘要:

A search for the standard model Higgs boson decaying to W+W- in pp collisions at sqrt(s) = 7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. The W+W- candidates are selected in events with two charged leptons and large missing transverse energy. No significant excess of events above the standard model background expectations is observed, and upper limits on the Higgs boson production relative to the standard model Higgs expectation are derived. The standard model Higgs boson is excluded in the mass range 129-270 GeV at 95% confidence level.
