在CMS上强产生两个同味反号轻子的SUSY粒子的实验研究

Searches for strong production of SUSY particles with two opposite-sign same-flavor leptons at CMS

Sergio Sánchez Cruz

摘要:

在末态具有两个相反符号、相同味道的轻子、喷流和缺少横动量的事件中,寻找超越标准模型的物理。在2016年CMS实验记录的$\sqrt{s} = $ 13 TeV pp碰撞的35.9 $\mathrm{fb}^{-1}$数据集中进行搜索。搜索目标是产生有色粒子的模型。模型被认为是,在双轻子不变的质量分布和模型中,Z玻色子出现在超对称粒子的衰变链中观察到的运动学边缘。这样的搜索已经在8 TeV pp碰撞以及13 TeV碰撞中进行。这个版本的搜索增加了额外的事件类别以及改进的背景估计程序,大大提高了搜索的灵敏度。结果被解释的超对称性的简化模型的上下文中。

英文摘要:

A search is presented for physics beyond the standard model in events with two opposite-sign, same-flavor leptons, jets and missing transverse momentum in the final state. The search is performed in a dataset of 35.9 $\mathrm{fb}^{-1}$ of $\sqrt{s} = $ 13 TeV pp collisions recorded by the CMS experiment in the year 2016. The search targets models in which a colored particle is produced. Models are considered, in which a kinematic edge is observed in the dilepton invariant mass distribution and models in which a Z boson arises in the decay chain of the SUSY particles. Such searches have been performed in 8 TeV pp collisions as well as 13 TeV collisions. This version of the search adds additional event categories as well as improved background estimation procedures substantially increasing the sensitivity of the search. The results are interpreted in the context of simplified models of Supersymmetry.
