论文摘要
使用$ 139〜 {\ text {fb}}}^{ - 1} $ $ \ sqrt {s} = 13 $ tev Proton-Proton-Proton碰撞数据记录的ATLAS检测器在LHC上记录的$ 139〜 {\ text {fb}} $ 139〜 {\ text {fb}} $ 139〜 {\ text {fb}} $ 139〜 {\ text {fb}} $ 139〜 {\ text {fb}} $进行搜索。 dijet不变质量（$ M_ {JJ} $）在该区域中搜索了至少一个孤立的电子或MUON的事件构建的分布，$ 0.22 <m_ {JJ} <6.3 $ tev <6.3 $ tev，超过了超过标准模型流程的平稳下降的多余。基于Lepton的存在触发，在发生的情况下，降低了最小横向动量阈值所施加的限制，以触发喷气机上的触发。这种方法可以比在包容性的Dijet搜索中探测较小的Dijet不变性质量，该群体针对各种新生理学模型，例如，其中与具有leptonly腐烂的$ w $ w $或$ z $ boson相关的新状态。没有发现与标准模型背景假设具有统计学意义的偏差。从检测器分辨率确定的宽度范围（到15％的共振质量）的宽度限制的限制范围为dijet不变质量，范围从0.25 TEV到6 TEV。在标准模型之外的几种情况下，也设置了限制，例如顺序标准模型，技术彩色模型，带电的希格斯玻色子模型和简化的暗物质模型。
A search for dijet resonances in events with at least one isolated charged lepton is performed using $139~{\text{fb}}^{-1}$ of $\sqrt{s}=13$ TeV proton-proton collision data recorded by the ATLAS detector at the LHC. The dijet invariant-mass ($m_{jj}$) distribution constructed from events with at least one isolated electron or muon is searched in the region $0.22 < m_{jj} < 6.3$ TeV for excesses above a smoothly falling background from Standard Model processes. Triggering based on the presence of a lepton in the event reduces limitations imposed by minimum transverse momentum thresholds for triggering on jets. This approach allows smaller dijet invariant masses to be probed than in inclusive dijet searches, targeting a variety of new-physics models, for example ones in which a new state is produced in association with a leptonically decaying $W$ or $Z$ boson. No statistically significant deviation from the Standard Model background hypothesis is found. Limits on contributions from generic Gaussian signals with widths ranging from that determined by the detector resolution up to 15% of the resonance mass are obtained for dijet invariant masses ranging from 0.25 TeV to 6 TeV. Limits are set also in the context of several scenarios beyond the Standard Model, such as the Sequential Standard Model, a technicolor model, a charged Higgs boson model and a simplified Dark Matter model.
