Description of the models:
We concentrate on anomalous quartic interaction among the electroweak gauge bosons that do not have a triple vertex associated to it. We describe these interactions using dimension eight effective operators assuming that the recently observed Higgs boson belongs to a SU(2)_{L} doublet; see the file quartic.pdf for further details. This model is an extension of the Standard Model (SM) implemented at http://feynrules.irmp.ucl.ac.be/wiki/StandardModel; for further details see this link.
The model labeled SM_LS0_LS1 contains the standard model interactions supplemented by the dimension eight operators L_{S,0} and L_{S,1} defined in the file quartic.pdf. These dimension eight effective operators modify the vertices WWWW, WWZZ, and WWZZ that can be a simple rescaling of the SM quartic interaction for a suitable choice of couplings.
The model labeled SM_LT012 contains the standard model interactions supplemented by the dimension eight operators L_{T,0} , L_{T,1} and L_{T,2} defined in the file quartic.pdf. These dimension eight effective operators give rise to anomalous WWWW, WWZZ, WWAZ, WWAA, AAAA, AAAZ, AAZZ, AZZZ, and ZZZZ vertices.
The model labeled SM_LM0123 contains the standard model interactions supplemented by the dimension eight operators L_{M,0} , L_{M,1} , L_{M,2} and L_{M,3} defined in the file quartic.pdf. These dimension eight effective operators give rise to anomalous WWWW, WWZZ, WWAZ, WWAA, AAZZ, AZZZ, and ZZZZ vertices.
The model labeled SM_LT8_LT9 contains the standard model interactions supplemented by the dimension eight operators L_{T,8} and L_{T,9} defined in the file quartic.pdf. These dimension eight effective operators give rise to anomalous AAAA, AAAZ, AAZZ, AZZZ, and ZZZZ vertices.

Instructions
The model files include the quartic and SM vertices in the unitary gauge. To generate models with any of the other dimension eight operators use the notebooks quartic_ls01.nb or quartic_lt89.nb as examples and include the additional interactions that are already defined in the model file quartic.fr. The anomalous couplings are set to 1 GeV^{4} by default, thus they should be conveniently chosen before the event generation.
