Measurement of the electroweak production of Z$\gamma$ and two jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV and constraints on anomalous quartic gauge couplings

CMS Collaboration

The first observation of the electroweak (EW) production of a Z boson, a photon, and two forward jets (Z$\gamma$jj) in proton-proton collisions at a center-of-mass energy of 13 TeV is p…
