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 non-linear and linear realizations of the $SU(2)_L \otimes U(1)_Y$ gauge symmetry.

ATLAS reports the observation of W⁺W⁻γ triboson production with 5.9σ significance and derives constraints on anomalous quartic gauge-boson couplings via effective field theory.
Projections show the μTRISTAN same-sign muon collider can significantly improve bounds on anomalous quartic gauge couplings via vector boson scattering in multiple final states at 2 and 6 TeV.
Spin-correlation asymmetries in same-sign WW production yield sensitivity to anomalous WWWW couplings comparable to transverse-mass distributions, and their combination improves Wilson-coefficient limits while respecting unitarity cuts.
The document reports the first year of activity of the VBSCan COST Action network on vector-boson scattering phenomenology and experiments from a 2018 workshop.
