摘要：
I present results through three loops for soft anomalous dimensions that control soft-gluon emission in processes involving the top quark. In particular I present results for channels in single-top production and top-pair production as well as for processes with new physics, including tZ, tZ ', t gamma, and tH(-) production. These calculations are ingredients to resummations at (NLL)-L-3 accuracy and to derivations of (NLO)-L-3 soft-gluon corrections.
