Contribution

It offers aN$^3$LO and aNNLO calculations for top production processes, improving the accuracy of theoretical predictions in high-energy collider physics.

Findings

aN$^3$LO results for $t\bar{t}$ cross section and distributions

aNNLO results for single-top production channels

Good agreement with recent Tevatron and LHC data

Abstract

I present results for high-order corrections from threshold resummation to cross sections and differential distributions in top-antitop pair production and in single-top production. I show aN$^3$LO results for the total $t{\bar t}$ cross section as well as for the top-quark transverse momentum ($p_T$) and rapidity distributions, and the top-quark forward-backward asymmetry in $t{\bar t}$ production. I compare with the most recent Tevatron and LHC data, including at 13 TeV. I also present aNNLO results for cross sections and $p_T$ distributions in $t$-channel, $s$-channel, and $tW$-channel single-top production.
