Classifying the bosonic quartic couplings

Abstract

The larger center-of-mass energy of the Large Hadron Collider Run 2 opens up the possibility of a more detailed study of the quartic vertices of the electroweak gauge bosons. Our goal in this work is to classify all operators possessing quartic interactions among the electroweak gauge bosons that do not exhibit triple gauge-boson vertices associated to them. We obtain all relevant operators in the nonlinear and linear realizations of the S U ( 2 ) L ⊗ U ( 1 ) Y gauge symmetry.
