Description
I present a calculation of higher-order corrections from NNLL threshold resummation for cross sections and differential distributions in top-antitop pair production and in single-top production. I show that soft-gluon threshold corrections are the dominant contribution to top-quark production and closely approximate exact results through NNLO. I show aN$^3$LO results for the total $t{\bar t}$ cross section, the top-quark $p_T$ and rapidity distributions, and the top-quark forward-backward asymmetry. I also present aNNLO results for total cross sections and $p_T$ distributions in $t$-channel, $s$-channel, and $tW$-channel single-top production.
