NNLOJET
A parton-level Monte Carlo event generator for the simulation of scattering processes at hadron colliders at next-to-next-to-leading order (NNLO) in QCD.
I am active part of the NNLOJET collaboration. I contributed to the implementation of the V+hadron process at NLO at pp colliders, and at ZH production process at electron-positron colliders, with Higgs hadronic decays at NNLO
