这封信首次探索了在大型强子对撞机上含有一个孤立电子或µ子、喷流和根S=7TeV质子-质子碰撞中丢失的横向动量的终态的超对称性。这些数据是由ATLAS实验在2010年记录的，相当于总积分光度为35PB(-1)。没有观察到超出标准模型背景期望值的情况。对最小超重力框架的参数设置了限制，扩展了之前的限制。在这个框架内，对于A(0)=0GeV，tanβ=3，u>；0，以及对于相等的夸克和胶子质量，低于700GeV的胶子质量在95%的置信度水平下被排除在外。
This Letter presents the first search for supersymmetry in final states containing one isolated electron or muon, jets, and missing transverse momentum from root 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. Within this framework, for A(0) = 0 GeV, tan beta = 3, and mu > 0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.
