In this paper, we discuss a connection between the diphoton channel ( γγ ) and triboson channels ( Zγγ , ZZγ , WWγ ) imposed by the SU(2)L×U(1)Y symmetry of the Standard Model (SM) in certain classes of models. To illustrate this idea we choose a simple model that has all these channels. In this model, the same physics can give rise to γ+MET instead of γγ and 2 bosons plus missing energy instead of 3-boson channels. We analyze existing constraints and previous searches and show that channels WWγ and especially Zγ+MET have a potential to discover new physics at the LHC.new physics: search forfinal state: two-photonmissing-energyinterpretation of experiments: CERN LHC Collsignaturetext::journal::journal article::research article
