在sqrt{s} = 7 TeV中使用带有一个轻子、喷流和丢失横向动量的末态和ATLAS探测器搜索超对称性

Search for supersymmetry using final states with one lepton, jets, and missing transverse momentum with the ATLAS detector in sqrt{s} = 7 TeV pp

The ATLAS Collaboration

摘要:

这封信提出了第一次搜索超对称性的最终状态包含一个孤立的电子或μ子,喷流,并从sqrt{s} = 7 TeV的质子-质子碰撞在LHC丢失的横向动量。这些数据由ATLAS实验在2010年记录,对应的总积分亮度为35 pb-1。未观察到超过标准模型背景预期的情况。对最小超重力框架的参数设定了限制,扩大了以前的限制。当A_0 = 0 GeV,tan β = 3,μ> 0,夸克质量和胶子质量相等时,在95%的置信水平下排除了700 GeV以下的胶子质量。

英文摘要:

This Letter presents the first search for supersymmetry in final states containing one isolated electron or muon, jets, and missing transverse momentum from sqrt{s} = 7 TeV proton-proton collisions at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35 pb-1. No excess above the standard model background expectation is observed. Limits are set on the parameters of the minimal supergravity framework, extending previous limits. For A_0 = 0 GeV, tan beta = 3, mu > 0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.
