I present an analysis of fully differential single-top-quark production plus jets at next-to-leading-order. I describe the effects of jet definitions, top-quark mass, and higher orders on the shapes and normalizations of the kinematic distributions, and quantify all theoretical uncertainties. I explain how to interpret next-to-leading-order jet calculations, and compare them to showering event generators. Using the program ZTOP, I show that HERWIG and PYTHIA significantly underestimate both s-channel and t-channel single-top-quark production, and propose a scheme to match the relevant samples to the next-to-leading-order predictions.

- NLO single-top production matched with shower in POWHEG: s- and t-channel contributions (2009, background): “Radiative corrections for single-top production have been known for years [4, 11, 12, 13, 14, 15, 16, 17, 18], while the implementation of these results into a next-to-leading-order Shower Monte Carlo (SMC), namely MC@NLO [19, 20], is more recent [21, 22].”

At the parton level, for example, the Monte Carlo for FeMtobarn processes (MCFM) [9,18,23,43] represents a convenient framework. For the t and the s-channel also the program ZTOP [7] can be used.
