VBFNLO is an event generator.
VBFNLO simulates vector boson fusion, double and triple vector boson production in hadronic collisions at next to leading order in the strong coupling constant. It includes Higgs and vector boson decays with full spin correlations and all off-shell effects. In addition, VBFNLO implements CP-even and CP-odd Higgs boson via gluon fusion, associated with two jets, at the leading order one loop level with the full top-quark and bottom-quark mass dependence in a generic two Higgs doublet model.
A variety of effects arising from beyond the Standard Model physics are implemented for selected processes. This includes anomalous couplings of Higgs and vector bosons and a Warped Higgsless extra dimension model.
An interface to Monte-Carlo generators is available via the BLHA interface, both versions 1 and 2.
