许多超对称场景的最终状态都带有非标准的最终状态对象。大质量粒子的产生可以导致被增强顶夸克或矢量玻色子和高pt b射流的产生。同时，由于非常软的轻子或喷流的存在，几乎质量简并粒子之间的跃迁可能会挑战标准重建。讲座将回顾在大型强子对撞机的ATLAS实验中，创新重建技术在超对称搜索中的应用。
Many supersymmetric scenarios feature final states with non-standard final state objects. The production of massive sparticles can lead to the production of boosted top quarks or vector bosons and high-pt b-jets. At the same time, transitions between nearly mass-degenerate sparticles can challenge the standard reconstruction because of the presence of very soft leptons or jets. The talk will review the application of innovative reconstruction techniques to supersymmetry searches within the ATLAS experiment at the LHC.
