Soft-gluon corrections for $tW$ production at N$^3$LO

High Energy Physics - Phenomenology 2017-08-23 v2

Abstract

I present approximate results that include third-order soft-gluon corrections for the associated production of a single top quark with a WW boson. The calculation uses expressions from soft-gluon resummation at next-to-next-to-leading-logarithm (NNLL) accuracy. From the NNLL resummed cross section I derive approximate next-to-next-to-next-to-leading order (aN3^3LO) cross sections for the process bgtWbg \rightarrow tW^- at LHC and Tevatron energies. The aN3^3LO top-quark transverse-momentum and rapidity distributions in tWtW production are also presented.
