Evidence for the electroweak Z gamma production in association with two jets and a search for anomalous quartic gauge couplings in pp collisions at sqrts = 8 TeV

Evidence for electroweak associated production of a Z boson, a photon and two jets, where the Z boson decays into electron or muon pairs, is presented. The measurement is based on a sample of proton-proton collisions collected by the CMS detector at a center of mass energy of 8 TeV, corresponding to an integrated luminosity of $19.7\,\rm{fb}^{-1}$. Limits on anomalous quartic gauge couplings are set with a binned profile likelihood method based on the $M_{Z\gamma}$ distribution.
