Vbfnlo: A parton level Monte Carlo for processes with electroweak bosons - Manual for Version 2.5.0

VBFNLO is a 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 (NLO) in the strong coupling constant, as well as Higgs boson plus two jet production via gluon fusion at the one-loop level. In the new release -- Version 2.5.0 -- several new processes have been added at NLO QCD: vector boson fusion production of a Higgs boson plus a photon, vector boson fusion production of a photon, W\gamma and WZ production plus a hadronic jet and the triboson production processes WW\gamma, ZZ\gamma, WZ\gamma, W\gamma\gamma, Z\gamma\gamma and \gamma\gamma\gamma. The code has been extended to run in the Minimal Supersymmetric Standard Model (MSSM), and electroweak corrections to Higgs boson production via weak boson fusion have been included. Anomalous gauge boson couplings can be used in new processes and the Three-Site Higgsless model has been implemented for several processes. The simulation of Higgs boson production via gluon fusion has been improved.
