I present higher-order radiative corrections from collinear and soft gluon emission for the associated production of a charged Higgs boson with a W boson. The calculation uses expressions from resummation at next-to-leading-logarithm accuracy. From the resummed cross section I derive approximate next-to-next-to-leading order (aNNLO) cross sections for the process b ¯b → H−W+ at LHC energies. The transverse-momentum and rapidity distributions of the charged Higgs boson are also calculated at aNNLO.
