- - This study focuses on the QCD (Quantum Chromodynamics) radiative corrections for the production of W and Z bosons in hadron collisions and presents a detailed calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory.
- - The authors utilize a new subtraction method to handle complex aspects like gamma-Z interference, the finite width of bosons, their leptonic decay, and spin correlations in their calculations.
- - Results from this work are implemented in a Monte Carlo program that allows users to apply specific kinematic cuts on final-state leptons and jets, with numerical examples provided for the Fermilab Tevatron and the LHC.
Article Abstract
We consider QCD radiative corrections to the production of W and Z bosons in hadron collisions. We present a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. To perform this NNLO computation, we use a recently proposed version of the subtraction formalism. The calculation includes the gamma-Z interference, finite-width effects, the leptonic decay of the vector bosons, and the corresponding spin correlations. Our calculation is implemented in a parton level Monte Carlo program. The program allows the user to apply arbitrary kinematical cuts on the final-state leptons and the associated jet activity and to compute the corresponding distributions in the form of bin histograms. We show selected numerical results at the Fermilab Tevatron and the LHC.
