在sqrt（s）= 8 TeV的质子-质子碰撞中寻找长寿命带电粒子对pMSSM、AMSB模型和其它模型的约束
Constraints on the pMSSM, AMSB model and on other models from the search for long-lived charged particles in proton-proton collisions at sqrt(s) = 8 TeV
摘要：
对唯象最小超对称标准模型（pMSSM）和反常介导的超对称破缺（AMSB）模型的类轻子长寿命区进行了严格的限制。这些限制来自最近在质子-质子碰撞中寻找长寿命带电粒子的结果，基于大型强子对撞机CMS探测器在8 TeV的质心能量下收集的数据。在考虑的pMSSM参数子空间中，95.9%的预测charginos的点的寿命至少为10 ns被排除在外。这些对pMSSM的限制是在LHC上首次获得的。在AMSB模型中，寿命大于100 ns，质量高达约800 GeV的Charginos也被排除在外。所描述的方法也可以用于对其他模型设置约束。
英文摘要：
Stringent limits are set on the long-lived lepton-like sector of the phenomenological minimal supersymmetric standard model (pMSSM) and the anomaly-mediated supersymmetry breaking (AMSB) model. The limits are derived from the results presented in a recent search for long-lived charged particles in proton-proton collisions, based on data collected by the CMS detector at a centre-of-mass energy of 8 TeV at the Large Hadron Collider. In the pMSSM parameter sub-space considered, 95.9% of the points predicting charginos with a lifetime of at least 10 ns are excluded. These constraints on the pMSSM are the first obtained at the LHC. Charginos with a lifetime greater than 100 ns and masses up to about 800 GeV in the AMSB model are also excluded. The method described can also be used to set constraints on other models.
