Abstract

I present theoretical results through three loops and N$^3$LO for soft-gluon corrections in a variety of processes involving top-quark production. In particular, I present results for total cross sections and differential distributions in single-top production and top-pair production as well as in top-quark processes with electroweak bosons and new physics.
