- Version: 3.0
- Release date: 27 May 2024
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. Electroweak corrections to Higgs production via vector boson fusion are also included in the SM and MSSM. 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 production via gluon fusion, associated with two jets, at the leading-order one-loop level.
A variety of effects arising from beyond the Standard Model physics are implemented for selected processes. Processes can be run in the MSSM, anomalous couplings of Higgs and vector bosons can be used, a Three-Site Higgsless model and a Warped Higgsless extra dimension model are included. The program offers the possibility of generating Les Houches Accord event files for most processes available at leading order.
Complete documentation, including instructions for building, installing and running VBFNLO, is available in the doc/Manual.pdf file.

To run VBFNLO:
./bin/vbfnlo --input=PATH/TO/INPUT_FILES
If the input -- e.g. vbfnlo.dat -- files are in the current directory, the --input can of course be omitted.
VBFNLO can be configured with several options, a complete list of which can be
found in the manual
or by running ./configure --help
.
The main options are:
-
--prefix=/path/to/install/dir
: Install VBFNLO in the location given by path. -
--enable-processes=LIST
: Comma-separated list of processes to enable. Options are: vbf, ggf, diboson, dibosonjet, triboson, tribosonjet, hjjj, top, qcdvvjj, qcdvjj, all_except_hexagons, all. Default: all_except_hexagons -
--enable-kk
: enable simulation of Kaluza-Klein resonances -
--enable-MPI
: use MPI parallelization -
--disable-NLO
: disable next-to-leading order QCD -
--enable-madgraph
: include code for MadGraph comparisons -
--enable-quad
: enable quad precision for difficult phase space points
Optional Packages:
