Soft-Gluon Corrections in FCNC Top-Quark Production via Anomalous Gluon Couplings

Understand

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.
