Release Note -- Vbfnlo-2.6.0

Vbfnlo is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), double and triple vector boson (plus jet) 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. This note briefly describes the main additional features and processes that have been added in the new release ‐ Vbfnlo Version 2.6.0. At NLO QCD diboson production (W , WZ, ZZ, Z and ), same-sign W pair production via vector boson fusion and the process Wj have been implemented (for which oneloop tensor integrals up to six-point functions are included). In addition, gluon induced diboson production can be studied separately at the leading order (oneloop) level. The diboson processes WW, WZ and W can be run with anomalous gauge boson couplings, and anomalous couplings between a Higgs and a pair of gauge bosons is included in WW, ZZ, Z and diboson production. The code has also been extended to include anomalous gauge boson couplings for single vector boson production via VBF, and a spin-2 model has been implemented for diboson pair production via vector boson fusion.
