    Parton level Monte Carlo program that computes the cross sections for vector boson production in pp and ppbar collisions up to NNLO in QCD perturbation theory. The calculation includes the gamma-Z interference, finite-width effects, the leptonic decay of the vector bosons and the corresponding spin correlations. The program allows the user to apply arbitrary cuts on the momenta of the partons and/or the leptons produced in the final state, and to easily obtain the desired distributions in the form of bin histograms.

    The DYRes program computes the cross section for vector boson production in pp or pp collisions. DYRes combines the calculation of the cross section up to next-to-next-to-leading order (NNLO) with the resummation of the logarithmically-enhanced contributions at small transverse momenta up to next-to-next-to-leading accuracy (NNLL) in QCD perturbation theory. The program includes the Z-gamma interference, finite-width effects and the leptonic decay of the vector boson with the corresponding spin correlations. The calculation retains the full kinematics of the vector boson and of its decay products, allowing the user to apply arbitrary cuts on these final-state kinematical variables, and to plot the corresponding distributions in the form of bin histograms. The decay modes included are W->lnu and Z/gamma*->ll. When referring to this program, please quote the references above.
