Abstract

A search for the electroweak production of charginos and sleptons decaying into final states with two electrons and/or muons is presented. The analysis is based on 139 fb^–1 of proton-proton collision data recorded by the ATLAS experiment at the Large Hadron Collider (LHC) at \(\sqrt s = 13\) TeV. Three R-parity-conserving scenarios are considered: the direct production of lightest chargino pairs with decays mediated by either W bosons or sleptons and the direct production of slepton pairs. No significant deviations from the Standard Model expectations are observed and limits at 95% Confidence Level (CL) are set on the masses of the relevant supersymmetric particles in each of these scenarios.

使用ATLAS探测器在LHC运行2中搜索具有两个轻子并缺少横向动量的最终状态的Charginos和Slepton的电弱生产

摘要

提出了寻找由两个电子和/或μ子衰变成最终状态的charginos和slepton的电弱产生的方法。该分析基于ATLAS实验在大强子对撞机（LHC）在\（\ sqrt s = 13 \） TeV下记录的139 fb ^–1质子-质子碰撞数据。考虑了三种R奇偶性守恒的情况：由W玻色子或slepton介导的衰变最轻的chargino对的直接产生和slepton对的直接产生。没有观察到与标准模型预期的显着偏差，并且在每种情况下，都对相关超对称粒子的质量设置了95％置信水平（CL）的限制。
