"Table 15" 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（CERN）-大型强子对撞机（LHC）。本数据集呈现了t道（t-channel）单顶夸克产生过程的详细测量结果。研究采用LHC上ATLAS实验（ATLAS）在8太电子伏特（TeV）质心系能量下质子-质子碰撞采集的$20.2 mathrm{fb}^{-1}$积分亮度数据。针对顶夸克（top quark）与反顶夸克（top-antiquark）的产生过程，本工作分别测量了总截面、 fiducial截面（fiducial cross-section）与微分截面（differential cross-section）。顶夸克产生的fiducial截面测量精度为5.8%，反顶夸克产生的fiducial截面测量精度为7.8%。顶夸克产生总截面的测量结果为$sigma_mathrm{tot}(tq) = 56.7^{+4.3}_{-3.8} mathrm{pb}$，反顶夸克产生总截面的测量结果为$sigma_mathrm{tot}(ar{t} q) = 32.9^{+3.0}_{-2.7} mathrm{pb}$，该结果与标准模型（Standard Model）的理论预言一致。此外，顶夸克与反顶夸克产生截面之比的测量值为$R_t=1.72 pm 0.09$。针对顶夸克与反顶夸克的横向动量（transverse momentum）和快度（rapidity）分布，研究在部分子层次（parton level）与粒子层次（particle level）上分别测量了对应的微分截面。针对t道散射过程中产生的伴随喷流，研究在粒子层次上测量了其横向动量与快度的微分截面。所有测量结果均与多种蒙特卡洛（Monte Carlo）预言以及现有可获取的固定阶量子色动力学（QCD）计算结果进行了比对。
