Search for Supersymmetry at ATLAS in final states with tau leptons

该学生的项目将成为ATLAS SUSY工作组的一部分。该学生将在ATLAS上寻找超越标准模型（BSM）的物理证据，这些证据是在电弱产生的事件中，SUSY粒子衰变为一个或多个tau轻子。学生将看到各种不同的签名：直接产生的状态（后来衰减为状态）；由电荷子和中性子介导的状态产生。学生将特别关注最终态，其中一个是强子衰变，另一个是轻子衰变。学生将设计最佳策略来定义信号区域，其中BSM事件相对于背景增强，并通过定义适当的控制区域来估计背景。预计该学生将在第二年在欧洲核子研究中心度过6到12个月。

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.
