在具有单个轻子、喷流和缺少横动量的事件中寻找sqrt(s)=7 TeV pp碰撞的超对称性

Search for supersymmetry in pp collisions at sqrt(s)=7 TeV in events with a single lepton, jets, and missing transverse momentum

CMS Collaboration

摘要:

结果报告从搜索物理超越标准模型在质子-质子碰撞在质心能量为7 TeV,专注于签名与一个单一的,孤立的,高横向动量轻子(电子或μ子),充满活力的射流,和大的失踪横向动量。该数据样本包括一个积分亮度的36个反皮巴,记录的CMS实验在大型强子对撞机。这项研究的动机是新物理学模型,包括超对称性。观测到的事件产额与使用从数据中获得的控制样本预测的标准模型背景一致。事件样本的特征与预期的t t-酒吧和W +喷流事件的生产是一致的。结果被解释在参数空间上的限制的标准模型的约束最小超对称扩展。

英文摘要:

Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of 7 TeV, focusing on the signature with a single, isolated, high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum. The data sample comprises an integrated luminosity of 36 inverse picobarns, recorded by the CMS experiment at the LHC. The search is motivated by models of new physics, including supersymmetry. The observed event yields are consistent with standard model backgrounds predicted using control samples obtained from the data. The characteristics of the event sample are consistent with those expected for the production of t t-bar and W +jets events. The results are interpreted in terms of limits on the parameter space for the constrained minimal supersymmetric extension of the standard model.
