We study heavy-flavor production at hadron colliders and present phenomenological results for the differential top-quark pair production cross section calculated in perturbative QCD at approximate next-to-next-to-leading order (NNLO) $O(\alpha_s^4)$. Methods of threshold resummation in QCD are utilized for this calculation which is implemented in the computer code \textsc{Difftop}. Transverse momentum and rapidity distributions of final-state top quarks are computed at the LHC center-of-mass energies and compared to recent measurements of the CMS and ATLAS collaborations, which are found to be in very good agreement.
