Abstract
We compute the O(αs) QCD corrections to charged triple vector boson production at a hadron collider, i.e., the processes pp→ZZW±+X and pp→W±W W±+X. Intermediate Higgs boson exchange effects, spin correlations from leptonic vector boson decays, and off shell contributions are all taken into account. Results are implemented in a fully flexible Monte Carlo program that allows for an easy customization of kinematical cuts and variation of the factorization and renormalization scales. We analyze the dependence of the differential cross sections under scale variations and present distributions where the QCD corrections strongly modify the leading-order results. © 2008 The American Physical Society.
