用ATLAS探测器在具有高能喷流和大的缺失横向动量的事件中寻找暗物质和其他新现象

Search for dark matter and other new phenomena in events with an energetic jet and large missing transverse momentum using the ATLAS detector

ATLAS Collaboration

摘要:

搜索结果的新现象,在最后的状态与一个充满活力的喷流和大失踪的横向动量的报告。该搜索使用质子-质子碰撞数据,对应于2015年和2016年在大型强子对撞机的ATLAS探测器上收集的13 TeV质量中心能量的36.1 fb ${}^{-1}$的积分亮度。事件需要至少有一个喷流的横向动量超过250 GeV,没有轻子($e$或$μ$)。几个信号区域被认为是与失踪的横向动量超过250 GeV的要求越来越高。在数据中的事件数和标准模型预测之间观察到良好的一致性。结果被翻译成排斥限制模型与成对产生的弱相互作用的暗物质候选人,大额外的空间维度,和超对称粒子在几个压缩的情况下。

英文摘要:

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton--proton collision data corresponding to an integrated luminosity of 36.1 fb${}^{-1}$ at a centre-of-mass energy of 13 TeV collected in 2015 and 2016 with the ATLAS detector at the Large Hadron Collider. Events are required to have at least one jet with a transverse momentum above 250 GeV and no leptons ($e$ or $μ$). Several signal regions are considered with increasing requirements on the missing transverse momentum above 250 GeV. Good agreement is observed between the number of events in data and Standard Model predictions. The results are translated into exclusion limits in models with pair-produced weakly interacting dark-matter candidates, large extra spatial dimensions, and supersymmetric particles in several compressed scenarios.
