The student's project will be part of the ATLAS SUSY working group. The student will search for evidence ofphysics beyond the standard model (BSM) at ATLAS in electro-weak produced events where SUSY particlesdecay to one of more tau leptons. The student will look at various different signatures: directly producedstaus (which later decay to taus); stau production mediated by Charginos and Neutralinos. The student willfocus in particular in the final states where one tau decays hadronically and one decays leptonically. Thestudent will device optimal strategies for defining signal regions where BSM events are enhanced with respectto backgrounds, and also estimate the backgrounds via definition of appropriate control regions. It isanticipated that the student will spend between 6 and 12 months at CERN in their second year of thestudentship.

该学生的项目将成为 ATLAS SUSY 工作组的一部分。学生将在 ATLAS 的电弱产生事件中寻找超出标准模型 (BSM) 的物理学证据，其中 SUSY 粒子衰变为多个 tau 轻子之一。学生将查看各种不同的签名：直接产生的 staus（随后衰减为 taus）； stau 的产生由 Charginos 和 Neutralinos 介导。学生将特别关注最终状态，其中一个 tau 蛋白以强子方式衰变，一个以轻子方式衰变。学生将设计最佳策略来定义 BSM 事件相对于背景得到增强的信号区域，并通过定义适当的控制区域来估计背景。预计学生将在第二年在 CERN 度过 6 至 12 个月的时间。
