N2 - In this work we present a calculation of both t-channel and s-channel single-top production at next-to-leading order in QCD for the Tevatron and for the LHC at a center-of-mass energy of 7 TeV. All the cross sections and kinematical distributions presented include leading nonfactorizable corrections arising from interferences of the production and decay subprocesses, extending previous results beyond the narrow-width approximation. The new off shell effects are found to be generally small, but can be sizeable close to kinematical endpoints and for specific distributions
