Description:
   'The observation of $WW\gamma$ production in proton-proton collisions at a center-of-mass energy of 13 TeV with an integrated
   luminosity of 138 fb$^{-1}$ is presented. The observed (expected) significance is 5.6 (5.1) standard deviations. Events are
   selected by requiring exactly two leptons (one electron and one muon) of opposite charge, moderate missing transverse momentum,
   and a photon. The measured fiducial cross section for $WW\gamma$ is 5.9 $\pm$ 0.8 (stat) $\pm$ 0.8 (syst) $\pm$ 0.7 (modeling) fb,
   in agreement with the next-to-leading order quantum chromodynamics prediction. The analysis is extended with a search for the
   associated production of the Higgs boson and a photon, which is generated by a coupling of the Higgs boson to light quarks.
   The result is used to constrain the Higgs boson couplings to light quarks.'
