This article presents measurements of the $t$-channel single top-quark $(t)$ and top-antiquark $(\\bar t)$ total production cross sections $\\sigma(tq)$ and $\\sigma(\\bar tq)$, their ratio $R_{t}=\\sigma(tq)/\\sigma(\\bar tq)$, and a measurement of the inclusive production cross section $\\sigma(tq+\\bar tq)$ in proton-proton collisions at $\\sqrt{s}~=~7~\\mathrm{TeV}$ at the LHC. Differential cross sections for the $tq$ and $\\bar tq$ processes are measured as a function of the transverse momentum and the absolute value of the rapidity of $t$ and $\\bar t$, respectively. The analyzed data set was recorded with the ATLAS detector and corresponds to an integrated luminosity of $4.59~\\mathrm{fb}^{-1}$. Selected events contain one charged lepton, large missing transverse momentum, and two or three jets. The cross sections are measured by performing a binned maximum-likelihood fit to the output distributions of neural networks. The resulting measurements are $\\sigma(tq)=46 \\pm 1(\\mathrm{stat})\\pm 6(\\mathrm{syst})~\\mathrm{pb}$, $\\sigma(\\bar tq)=23 \\pm 1(\\mathrm{stat})\\pm 3(\\mathrm{syst})~\\mathrm{pb}$, $R_{t}=2.04 \\pm 0.13(\\mathrm{stat})\\pm 0.12(\\mathrm{syst})$, and $\\sigma(tq+\\bar tq)=68 \\pm 2(\\mathrm{stat})\\pm 8(\\mathrm{syst})~\\mathrm{pb}$, consistent with the Standard Model expectation. The uncertainty on the measured cross sections is dominated by systematic uncertainties, while the uncertainty on $R_{t}$ is mainly statistical. Using the ratio of $\\sigma(tq+\\bar tq)$ to its theoretical prediction, and assuming that the top-quark-related CKM matrix elements obey the relation $|V_{tb}|\\gg |V_{ts}|$, $|V_{td}|$, we determine $|V_{tb}|=1.02 \\pm 0.07$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.64385.v2/t1","@type":"Dataset","description":"Predicted and observed events yields for the 2-jet and 3-jet channels considered in this measurement.
