Measurement of the Z $γ$ production cross section and search for anomalous neutral triple gauge couplings in pp collisions at $s$ = 13 TeV

CMS Collaboration

A measurement of the fiducial cross section of the associated production of a Z boson and a high- $p_{T}$ photon, where the Z decays to two neutrinos, and a search for anomal…
