Soft-Gluon Corrections in FCNC Top-Quark Production via Anomalous Gluon Couplings (1404.7488v2)

Published 29 Apr 2014 in hep-ph

Abstract: We present a calculation of soft-gluon corrections in FCNC top-quark production via anomalous $t$-$q$-$g$ couplings. The soft anomalous dimension matrix is explicitly calculated at one-loop accuracy. This calculation allows threshold resummation at next-to-leading-logarithm accuracy. We also derive expressions for the soft-gluon corrections at NLO and at NNLO.
