Project Description

VBFNLO is a fully flexible parton level Monte Carlo program for the simulation of vector boson fusion, double and triple vector boson production in hadronic collisions at next to leading order in the strong coupling constant. VBFNLO 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. The program offers the possibility to generate Les Houches Accord event files for all processes available at leading order.

All implemented processes can be found here.

The current version 2.7.1 from August 2015 can be downloaded here.

There is also a beta version – 3.0.0 beta 5 – from February 2018, which can be downloaded here.

Alternatively, you can get the code from our public repository at GitHub.


The following papers should be cited while using VBFNLO: arXiv:1404.3940, arXiv:1107.4038, arXiv:0811.4559.

Additionally, the original literature on which the specific process is based on should be cited as well. Relevant publications are printed in the header of the program output. A list of papers concerning parts of VBFNLO is collected in Publications.
