Abstract

I present calculations of approximate corrections from NNLL soft-gluon resummation for total and differential cross sections in top-antitop pair production and single-top production in hadronic collisions. I show that soft-gluon corrections from partonic threshold are the dominant contribution to top-quark production and closely approximate exact results. I present aN3^3LO results for the total ttˉt{\bar t} cross section, the top-quark pTp_T and rapidity distributions, and the top-quark forward-backward asymmetry. I also provide updates for single-top production in the tt, ss, and tWtW channels. Finally, I discuss top-quark production via anomalous gluon couplings.
