Higher-order QCD corrections to vector boson production at hadron colliders / G. Ferrera. - In: POS PROCEEDINGS OF SCIENCE. - ISSN 1824-8039. - (2009). ((Intervento presentato al convegno European Physical Society Europhysics Conference on High Energy Physics, tenutosi a Krakow nel 2009.
Abstract:
We present two recent results on higher-order QCD corrections to the production of vector bosons in hadron collisions. 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 study the perturbative uncertainty of the results and we compare our prediction with Tevatron data for Z bosons production. Moreover we discuss a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. The 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.
