I present approximate results that include third-order soft-gluon corrections for the associated production of a single top quark with a W 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 ( a N 3 LO ) cross sections for the process b g → t W − at LHC and Tevatron energies. The a N 3 LO top-quark transverse-momentum and rapidity distributions in t W production are also presented.
