论文摘要
我们介绍了Lepton+JETS通道中的$ t \ bar {t} $最终状态中单分和双分截面的测量值，并考虑到粒子和parton级别，并考虑了分析和增强的拓扑。完全校正的光谱作为顶级Quark的功能以及$ t \ bar {t} $系统运动学变量和PP碰撞中的JET乘数在$ \ sqrt {s} = 13 $ tev的数据中，在2015年和2016年收集的Atlas detector，以对应于LHC，以对应于LHC。 $ 36 \，\ mathrm {fb}^{ - 1} $。测量结果提供了有关Quark生产和衰减的详细信息，从而实现了现代蒙特卡洛发生器的精确测试以及最新的固定级标准模型预测。在降低的系统不确定性W.R.T.中观察到理论预测与数据之间的良好一致性。先前的地图集测量。
We present measurements of single- and double-differential cross-sections in $t\bar{t}$ final states in the lepton+jets channel, unfolded to particle and parton levels with both resolved and boosted topologies considered. Fully corrected spectra are presented as functions of the top-quark as well as $t\bar{t}$ system kinematic variables and jet multiplicities in data from pp collisions at $\sqrt{s}=13$ TeV collected in 2015 and 2016 by the ATLAS detector at the LHC, corresponding to integrated luminosity of $36\,\mathrm{fb}^{-1}$ . Measurements provided detailed information on the top-quark production and decay, enabling precision tests of modern Monte Carlo generators as well as latest fixed-order Standard Model predictions. Good agreement between the theoretical predictions and the data is observed within reduced systematic uncertainties w.r.t. previous ATLAS measurements.
