We describe these interactions using 13 dimension eight effective operators assuming that the recently observed Higgs boson belongs to a SU(2) doublet; see the file ''quartic.pdf'' for further details. This model 14 is an extendion of the Standard Model (SM) implemented at [http://feynrules.irmp.ucl.ac.be/wiki/StandardModel]; for further details see this link. 13 dimension eight effective operators assuming that the recently observed Higgs boson belongs to a SU(2),,L,, doublet; see the file 14 [http://feynrules.irmp.ucl.ac.be/attachment/wiki/AnomalousGaugeCoupling/quartic.pdf quartic.pdf] for further details. This model 15 is an extension of the Standard Model (SM) implemented at [http://feynrules.irmp.ucl.ac.be/wiki/StandardModel]; for further details see this link. 15 16 16 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.17 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 [http://feynrules.irmp.ucl.ac.be/attachment/wiki/AnomalousGaugeCoupling/quartic.pdf 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. 17 18 18 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.19 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 [http://feynrules.irmp.ucl.ac.be/attachment/wiki/AnomalousGaugeCoupling/quartic.pdf quartic.pdf].

The anomalous couplings are set to 1 GeV^4^ by default, thus they should be conveniently chosen before the event generation 35 .
