Description
A study of the Standard Model (SM) three electroweak boson
production, WV$\gamma$ where V = W or Z gauge boson, is
presented concerning events with a leptonically
decaying W boson accompanied by a photon and two or more
jets. We are using the full 2012 dataset, of proton-proton
collisions at a center-of-mass energy of 8 TeV and an integrated
luminosity of 20 fb$^{-1}$, collected by the CMS detector at the
Large Hadron Collider (LHC). WV$\gamma$ production final states
may be sensitive to anomalous WW$\gamma\gamma$ and WWZ$\gamma$
quartic couplings. In light of the recent discovery of a
Higgs-like particle, we investigate, in
a model independent way, any deviation of gauge boson couplings
with respect to the SM prediction by setting limits on the
anomalous quartic gauge couplings (aQGC) for WW$\gamma\gamma$
and WWZ$\gamma$. Upper limits at 95\% confidence level are obtained,
with and without a form factor.
