Measurements of the pp $\to$ W${}^{\pm }\gamma \gamma$ and pp $\to$ Z$\gamma \gamma$ cross sections at $\sqrt{s}=$ 13 TeV and limits on anomalous quartic gauge couplings

CMS Collaboration

The cross section for W or Z boson production in association with two photons is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data set corresponds…
