Description

I present results for two-loop soft anomalous dimensions, which are derived from dimensionally regularized diagrams with eikonal quark lines and control soft-gluon emission in hard-scattering processes. Detailed results for the UV poles of the eikonal integrals will be shown for massive quarks, and the massless limit will also be taken. The construction of soft anomalous dimensions at two-loops allows soft-gluon resummations at NNLL accuracy.
