"Table 4" 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.

- CERN-LHC：本数据集呈现了t道单顶夸克产生过程的高精度测量结果。该测量使用了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的数据。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。顶夸克与顶反夸克的fiducial截面测量精度分别为5.8%与7.8%。顶夸克产生过程的总截面测量结果为$sigma_{
m tot}(tq)=56.7_{-3.8}^{+4.3} mathrm{pb}$，顶反夸克产生过程的总截面测量结果为$sigma_{
m tot}(ar{t}q)=32.9_{-2.7}^{+3.0} mathrm{pb}$，二者均与标准模型（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的测量结果为$R_t=1.72pm0.09$。针对顶夸克与顶反夸克的横向动量与快度分布，分别在部分子层次（parton level）与粒子层次（particle level）上测量了其微分截面。针对t道散射伴随喷注的横向动量与快度分布，在粒子层次上测量了其微分截面。所有测量结果均与多种蒙特卡洛（Monte Carlo）预言以及可获得的固定阶量子色动力学（Quantum Chromodynamics, QCD）计算结果进行了比对。
