长寿命态出现在各种超对称模型中，如规范介导的超对称破缺模型。在大型强子对撞机的实验中，长寿命状态不仅对超对称性信号的发现很有用，而且对研究超粒子的详细性质也很有用。讨论了一种在长寿命框架中获取超粒子自旋和手性信息的方法。我们还表明，这样的研究可以用来区分超对称性模型与其他新物理模型，如普遍的额外维度模型。
Long-lived stau shows up in various supersymmetric models, like gauge-mediated supersymmetry (SUSY) breaking model. At the LHC experiment, long-lived stau is useful not only for the discovery of SUSY signals but also for the study of the detailed properties of superparticles. We discuss a method to obtain information on spins and chiralities of superparticles in the framework with long-lived stau. We also show that such a study can be used to distinguish SUSY model from other models of new physics, like the universal extra dimension model.
