We consider the production of a Standard Model Higgs boson decaying to bottom quarks in association with a vector boson W/Z in hadron collisions. We present a fully exclusive calculation of QCD radiative corrections both for the production cross section and for the Higgs boson decay rate up to next-to-next-to-leading order (NNLO) accuracy. Our calculation also includes the leptonic decay of the vector boson with finite-width effects and spin correlations. We consider typical kinematical cuts applied in the experimental analyses at the Large Hadron Collider (LHC) and we find that the full NNLO QCD corrections significantly decrease the accepted cross section and have a substantial impact on the shape of distributions. We point out that these additional effects are essential to obtain precise theoretical predictions to be compared with the LHC data.

Original abstract
We consider the production of a Standard Model Higgs boson decaying to bottom quarks in association with a vector boson W/Z in hadron collisions. We present a fully exclusive calculation of QCD radiative corrections both for the production cross section and for the Higgs boson decay rate up to next-to-next-to-leading order (NNLO) accuracy. Our calculation also includes the leptonic decay of the vector boson with finite-width effects and spin correlations. We consider typical kinematical cuts applied in the experimental analyses at the Large Hadron Collider (LHC) and we find that the full NNLO QCD corrections significantly decrease the accepted cross section and have a substantial impact on the shape of distributions. We point out that these additional effects are essential to obtain precise theoretical predictions to be compared with the LHC data.

To define an expansion of Eq. ([ref]) in $α_s$, we follow Ref. [ref] , write the production cross section and the decay width to $b b̅$ as an expansion in $α_s$ d σ_WH = ∑_i=0^∞ d σ_WH^(i), d Γ_b b̅ = ∑_i=0^∞ d Γ_b b̅^(i), and introduce d γ^(i) = ∑_j=0^i d Γ_b b̅^(j)/∑_j=0^i Γ_b b̅^(j).

It is worth noticing that the uncertainty induced by scale variations ranges between 2% and 4% for both the NNLO and NNLO+NNLL distributions, as shown in Fig. [ref], and this estimate is somewhat larger than the value found in other studies on HW associate production Ref. [ref] .
