The inclusive cross section is found to be $275.6 \pm 6.1 \,\text {(stat)} \pm 37.8 \,\text {(syst)} \pm 7.2 \,\text {(lumi)} $   $\text {\,pb}$ . The normalized differential cross sections are measured as a function of the top quark transverse momenta, $p_{\mathrm {T}}$ , and compared to predictions from quantum chromodynamics. The results are reported at detector, parton, and particle levels. In all cases, the measured top quark $p_{\mathrm {T}}$ spectra are significantly softer than theoretical predictions.engjournal article2019-02-04
