论文摘要

标准模型的几个扩展预测了LHC处的暗物质颗粒的产生。搜索与$ \ ell^\pmνq\ bar q'$最终状态$ \ ell = e,μ$相关的深色希格斯玻色子腐烂而产生的暗物质粒子。该分析使用$ pp $的139 fb $^{ - 1} $ collisions collisions the Atlas检测器在13 TEV的质量中记录。 $ w^\ pm \ to q \ bar q'$衰减是通过量热计的喷气机或轨道辅助的重凝集的喷头重建的,这是一种旨在从热量表中使用Jets刺激的Quarks来解决密集拓扑的技术。发现观察到的数据与标准模型预测一致。黑暗希格斯玻色子块的场景排除在140至390 GEV之间。

Several extensions of the Standard Model predict the production of dark matter particles at the LHC. A search for dark matter particles produced in association with a dark Higgs boson decaying into $W^{+}W^{-}$ in the $\ell^\pmνq \bar q'$ final states with $\ell=e,μ$ is presented. This analysis uses 139 fb$^{-1}$ of $pp$ collisions recorded by the ATLAS detector at a centre-of-mass energy of 13 TeV. The $W^\pm \to q\bar q'$ decays are reconstructed from pairs of calorimeter-measured jets or from track-assisted reclustered jets, a technique aimed at resolving the dense topology from a pair of boosted quarks using jets in the calorimeter and tracking information. The observed data are found to agree with Standard Model predictions. Scenarios with dark Higgs boson masses ranging between 140 and 390 GeV are excluded.
