Abstract: I present results for two-loop soft anomalous dimensions, which are derivedfrom dimensionally regularized diagrams with eikonal quark lines and controlsoft-gluon emission in hard-scattering processes. Detailed results for the UVpoles of the eikonal integrals are shown for massive quarks, and the masslesslimit is also taken. The construction of soft anomalous dimensions at two-loopsallows soft-gluon resummations at NNLL accuracy.
