NNLOPS accurate associated HZ production with H -> b(b)over-bar decay at NLO

We present a next-to-next-to-leading order (NNLO) accurate description of associated HZ production, followed by the Higgs boson decay into a pair of b-quarks treated at next-to-leading order (NLO), consistently matched to a parton shower (PS). The matching is achieved by performing reweighting of the HZJ-MiNLO events, using multi-dimensional distributions that are fully-differential in the HZ Born kinematics, to the NNLO results obtained by using the MCFM-8.0 fixed-order calculation. Additionally we include the gg -> HZ contribution to the discussed process that appears at the O(alpha(2)(s)). We present phenomenological results obtained for 13TeV hadronic collisions.
