This analysis shows that soft-gluon resummation significantly impacts QCD corrections in single-top-quark production.
I present results for s-channel single-top-quark production using soft-gluon resummation. I show that the soft-gluon corrections provide the dominant contribution to the QCD corrections, and that they approximate very well the exact results through NNLO. Furthermore, approximate N³LO corrections are computed. The calculation treats the final-state b-quarks as massless but I also show how to extend the formalism to the case of massive b-quarks. The higher-order corrections are large at LHC energies and they improve the theoretical accuracy.
