The data set corresponds to an integrated luminosity of $137\\,\\mathrm{fb}^{-1}$ collected by the CMS experiment at the LHC. The $\\mathrm{W}\\to\\ell\\nu$ and $\\mathrm{Z}\\to\\ell\\ell$ decay modes (where $\\ell=\\mathrm{e},\\mu$) are used to extract the $\\mathrm{W}\\gamma\\gamma$ and $\\mathrm{Z}\\gamma\\gamma$ cross sections in a phase space defined by electron (muon) with transverse momentum larger than $35\\,(30)\\,\\mathrm{GeV}$ and photon transverse momentum larger than $20\\,\\mathrm{GeV}$. The measured cross sections in this phase space are $\\sigma(\\mathrm{W}\\gamma\\gamma)=13.6^{+1.9}_{-1.9}\\,\\mathrm{(stat)}^{+4.0}_{-4.0}\\,\\mathrm{(syst)}\\pm 0.08\\,\\mathrm{(PDF + scale)}\\,\\mathrm{fb}$ and $\\sigma(\\mathrm{Z}\\gamma\\gamma)=5.41^{+0.58}_{-0.55}\\,\\mathrm{(stat)}^{+0.64}_{-0.70}\\,\\mathrm{(syst)}\\pm 0.06\\,\\mathrm{(PDF + scale)}\\,\\mathrm{fb}$. Limits on anomalous quartic gauge couplings are set in the framework of an effective field theory with dimension-8 operators.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.113759.v1/t1","@type":"Dataset","description":"Distribution of the transverse momentum of the diphoton system for the $\\mathrm{W}\\gamma\\gamma$ electron channel.
