Description
We consider QCD radiative corrections and their to the production of vector bosons in hadron collisions.
We present a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. Our calculation is implemented in a parton level Monte Carlo program which allows the user to apply
arbitrary kinematical cuts on the final-states and to compute the corresponding distributions in the form of bin histograms. We show selected numerical results at the Tevatron and the LHC.
We discuss the resummation of logarithmic-enhanced QCD corrections at small values of qT and the matching procedure to consistently combine resummation with the fixed order perturbative result at intermediate and large qT. We present a study of the scale dependence and of the perturbative uncertainty of our results. We compare numerical results for e+e- pairs from the decay of Z bosons with the available Tevatron data.
