如果超对称（SUSY）具有压缩光谱，则大型强子对撞机的电流限制可以大大减少。我们采取可能的“最坏情况”场景，其中光阑、夸克和胶子质量的组合随着最轻的 SUSY 粒子的质量而退化。为了准确导出模型中的限制，在描述 QCD 辐射时必须小心，我们对此进行了详细检查。然后通过考虑所有 7 TeV 强子 SUSY 和单射流搜索来产生质量下限。还介绍了随着质量分裂的变化极限的演变。
If Supersymmetry (SUSY) has a compressed spectrum the current limits from the LHC can be drastically reduced. We take possible `worst case' scenarios where combinations of the stop, squark and gluino masses are degenerate with the mass of the lightest SUSY particle. To accurately derive limits in the model, care must be taken when describing QCD radiation and we examine this in detail. Lower mass bounds are then produced by considering all the 7 TeV hadronic SUSY and monojet searches. The evolution of the limits as the mass splitting is varied is also presented.
