Associated production of a Higgs boson at NNLO

In this paper we present a next-to-next-to leading order (nnlo) calculation of the production of a higgs boson in association with a massive vector boson. we include the decays of the unstable higgs and vector bosons, resulting in a fully flexible parton-level monte carlo implementation. we also include all $$ mathcal{o}left({alpha}_s^2right) $$ contributions that occur in production for these processes: those mediated by the exchange of a single off-shell vector boson in the s-channel, and those which arise from the coupling of the higgs boson to a closed loop of fermions. we study final states of interest for run ii phenomenology, namely $$ hto boverline{b} $$ , γγ and ww ∗. the treatment of the $$ hto boverline{b} $$ decay includes qcd corrections at nlo. we use the recently developed n -jettiness regularization procedure, and study its viability in the presence of a large final-state phase space by studying pp → v (h → ww ∗) → leptons.
