利用$\sqrt{s} =13$ ATLAS质子-质子碰撞寻找大喷注多重数和缺少横动量的末态新现象

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum with ATLAS using $\sqrt{s} =13$ TeV proton--proton collisions

ATLAS Collaboration

摘要:

结果报告的搜索新的现象,如超对称粒子的生产,可以观察到在高能质子-质子碰撞。事件与大量的喷流,连同失踪的横向动量从未观测到的粒子,被选中。分析的数据是2015年期间ATLAS实验使用大型强子对撞机上13 TeV质量中心质子-质子碰撞记录的,对应于3.2 fb $^{-1}$的积分亮度。检索选择了具有从$\ge 7$到$\ge 10$喷流的各种喷流多重性的事件,以及具有各种$b$ -喷流多重性要求的事件,以提高灵敏度。未观察到超出标准模型预期的情况。结果被解释在两个超对称模型,其中胶子质量高达1400 GeV被排除在95%的置信水平,显着扩展以前的限制。

英文摘要:

Results are reported of a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton--proton collisions. Events with large numbers of jets, together with missing transverse momentum from unobserved particles, are selected. The data analysed were recorded by the ATLAS experiment during 2015 using the 13 TeV centre-of-mass proton--proton collisions at the Large Hadron Collider, and correspond to an integrated luminosity of 3.2 fb$^{-1}$. The search selected events with various jet multiplicities from $\ge 7$ to $\ge 10$ jets, and with various $b$-jet multiplicity requirements to enhance sensitivity. No excess above Standard Model expectations is observed. The results are interpreted within two supersymmetry models, where gluino masses up to 1400 GeV are excluded at 95% confidence level, significantly extending previous limits.
