The inclusive cross section is found to be 275.6±6.1(stat)±37.8(syst)±7.2(lumi) \,pb. The normalized differential cross sections are measured as a function of the top quark transverse momenta, pT, and compared to predictions from quantum chromodynamics. The results are reported at detector, parton, and particle levels. In all cases, the measured top quark pT spectra are significantly softer than theoretical predictions.This article is distributed under the terms of the Creative Commons Attribution 4.0 International License, which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.http://creativecommons.org/licenses/by/4.0/Article10.1140/epjc/s10052-016-3956-5openAccess
