Abstract
In this article we generalise Powheg nexttoleading order parton shower Nlops simulations of vector boson production and vector boson production in association with a single jet to give matrix element corrected Menlops simulations In so doing we extend and provide for the first time an exact and faithful implementation of the Menlops formalism in hadronic collisions We also consider merging the resulting event samples according to a phase space partition defined in terms of an effective jet clustering scale The merging scale is restricted such that the component generated by the associated production simulation does not impact on the NLO accuracy of inclusive vector boson production observables The dependence of the predictions on the unphysical merging scale is demonstrated Comparisons with Tevatron and LHC data are presentedThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
