Two-loop soft anomalous dimensions for single top quark associated production with a W- or H-
arXiv:1005.4451 · doi:10.1103/PhysRevD.82.054018
Abstract
I present results for the two-loop soft anomalous dimensions for associated production of a single top quark with a W boson or a charged Higgs boson. The calculation uses expressions for the massive cusp anomalous dimension, which are presented in different forms, and it allows soft-gluon resummation at next-to-next-to-leading-logarithm (NNLL) accuracy. From the NNLL resummed cross section I derive approximate NNLO cross sections for bg -> tW- and bg -> tH- at LHC energies of 7, 10, and 14 TeV.
