Three-loop soft anomalous dimensions for top-quark processes

Abstract

I present results for soft anomalous dimensions through three loops for several processes involving the production of top quarks. In particular, I discuss single-top and top-pair production. I also present some numerical results for double-differential distributions in $t\bar{t}$ production through approximate N${}^3$LO.
