"Table 18" of "Fiducial, total and differential cross-section measurements of $t$-channel single top-quark production in $pp$ collisions at 8 TeV using data collected by the ATLAS detector"

- CERN-LHC. Detailed measurements of $t$-channel single top-quark production are presented. They use $20.2~\mathrm{fb}^{-1}$ of data collected by the ATLAS experiment in proton--proton collisions at a centre-of-mass energy of 8 TeV at the LHC. Total, fiducial and differential cross-sections are measured for both top-quark and top-antiquark production. The fiducial cross-section is measured with a precision of $5.8~\%$ (top quark) and $7.8~\%$ (top antiquark), respectively. The total cross-sections are measured to be $\sigma_\mathrm{tot}(tq) = 56.7^{+4.3}_{-3.8}\;\mathrm{pb}$ for top-quark production and $\sigma_\mathrm{tot}(\bar{t} q) = 32.9^{+3.0}_{-2.7}\;\mathrm{pb}$ for top-antiquark production, in agreement with the Standard Model prediction. In addition, the ratio of top-quark to top-antiquark production cross-sections is determined to be $R_t=1.72 \pm 0.09$. The differential cross-sections as a function of the transverse momentum and rapidity of both the top quark and the top antiquark are measured at both the parton and particle levels. The transverse momentum and rapidity differential cross-sections of the accompanying jet from the $t$-channel scattering are measured at particle level. All measurements are compared to various Monte Carlo predictions as well as to fixed-order QCD calculations where available.

- 欧洲核子研究中心大型强子对撞机（CERN-LHC）相关数据集：本文呈现了t道（t-channel）单顶夸克产生过程的详细测量结果。该分析使用了LHC上ATLAS实验在质心系能量8 TeV的质子-质子对撞中采集的20.2 fb⁻¹的对撞数据。研究针对顶夸克与顶反夸克的产生过程，分别测量了总截面、 fiducial截面（fiducial cross-section）与微分截面。其中顶夸克产生的fiducial截面测量精度为5.8%，顶反夸克产生的为7.8%。顶夸克产生的总截面测量结果为$sigma_{mathrm{tot}}(tq) = 56.7^{+4.3}_{-3.8} mathrm{pb}$，顶反夸克产生的总截面为$sigma_{mathrm{tot}}(ar{t}q) = 32.9^{+3.0}_{-2.7} mathrm{pb}$，上述结果与标准模型（Standard Model）的理论预言相符。此外，顶夸克与顶反夸克产生截面之比被测定为$R_t = 1.72 pm 0.09$。本研究在部分子（parton）与粒子两个层面上，测量了以顶夸克和顶反夸克的横动量（transverse momentum）及快度（rapidity）为变量的微分截面。同时在粒子层面上，测量了t道散射伴随喷注的横动量与快度微分截面。所有测量结果均与多种蒙特卡洛（Monte Carlo, MC）预言，以及现有可获得的固定阶量子色动力学（QCD）计算结果进行了比对。
