Soft-gluon corrections for the associated production of a single top quark and a Higgs boson
We discuss soft-gluon resummation for the associated production of a single top quark and a Higgs boson (tqH production) in single-particle-inclusive kinematics. We present analytical results for the higher- order corrections and numerical results for the cross sections at LHC energies. We calculate approximate next-to-next-to-leading-order total rates, including scale dependence and uncertainties from parton distributions, as well as top-quark transverse-momentum and rapidity distributions. In all cases we find that the soft-gluon corrections are dominant and provide important contributions to the total and differential cross sections.
