Why is that interesting? If there are other particles/forces that interact with (or decay to) Z and/or photon, this measurement could be sensitive to them. So this measurement sets almost completely model-independent limits on the strength of new physics i

#CMSpaper 504: Zγ production with invisible Z. This Phys.Lett.B paper on the production of Z bosons plus photon also discusses constraints on #newphysics interactions between Z bosons and photons. It uses Z decays to neutrinos to avoid ambiguities in decay
