'''Anomalous quartic electroweak gauge-boson Interactions''' '''Authors:''' O.J.P. Eboli (eboli AT fma.if.usp.br) M.C. Gonzalez-Garcia (concha AT max2.physics.sunysb.edu) '''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)doublet.
