用ATLAS探测器在$\sqrt{s}=13$ TeV质子-质子碰撞中搜索具有一个或两个喷流的喷流对质量分布中的共振,

Search for resonances in the mass distribution of jet pairs with one or two jets identified as $b$-jets in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

摘要:

在0.57 TeV到7 TeV的双喷流质量范围内,对在LHC与ATLAS探测器的$pp$碰撞中衰变为含b-强子喷流的新共振进行了研究。该数据集对应于2015年和2016年在$\sqrt{s} = 13$ TeV收集的高达36.1 fb $^{-1}$的积分亮度。在95%CL下提供了几种类型信号假设的相应信号质量参数的横截面上限和下限。此外,95%CL上限设置在横截面上的新的过程,将产生高斯形的信号中的di-b-jet质量分布。

英文摘要:

A search for new resonances decaying into jets containing b-hadrons in $pp$ collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 TeV to 7 TeV. The dataset corresponds to an integrated luminosity of up to 36.1 fb$^{-1}$ collected in 2015 and 2016 at $\sqrt{s} = 13$ TeV. No evidence of a significant excess of events above the smooth background shape is found. Upper cross-section limits and lower limits on the corresponding signal mass parameters for several types of signal hypotheses are provided at 95% CL. In addition, 95% CL upper limits are set on the cross-sections for new processes that would produce Gaussian-shaped signals in the di-b-jet mass distributions.
