摘要：

We present results for the Higgsstrahlung process within the GENEVA Monte Carlo framework. We combine the fully differential next-to-next-to-leading order (NNLO) calculation with the higher-order resummation in the 0-jettiness resolution variable (beam thrust). The resulting parton-level events are further showered and hadronized by PYTHIA8. The beam thrust resummation is carried out to next-to-next-to-leading logarithmic accuracy, consistently incorporating all singular virtual and real NNLO corrections. It thus provides a natural perturbative connection between the NNLO calculation and the parton shower regime, including a systematic assessment of perturbative uncertainties. In this way, observables which are inclusive over the additional radiation are correct to NNLO, while the description of 0-jet -like resummation variables is improved beyond the parton shower approximation. We provide predictions for the 13 TeV LHC.
