$W^{+}{W}^{-}$ production at NNLO+PS

Abstract

We present predictions for $W^{+}{W}^{-}$ production (with exact decays) that are next-to-next-to-leading order (NNLO) accurate and consistently matched to a parton shower. The matching is achieved by upgrading, with MiNLO, the NLO calculation of $W^{+}{W}^{-}+1$ jet production, in such a way that NLO accuracy is guaranteed for $W^{+}{W}^{-}$ inclusive observables, and by performing subsequently a reweighting of the WWJ-MiNLO events, differential in the $W^{+}{W}^{-}$ Born variables, to the NNLO results obtained with MATRIX.
