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 \\text{(stat)} \\pm 0.8 \\text{(syst)} \\pm 0.7 \\text{(modeling)} fb$, in agreement with the next-to-leading order quantum chromodynamics prediction. The analysis is extended with a search for the associated production of the Higgs boson and a photon, which is generated by a coupling of the Higgs boson to light quarks. The result is used to constrain the Higgs boson couplings to light quarks.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t1","@type":"Dataset","description":"The Measured and theoretical cross sections in the fiducial volume.","name":"Fiducial Cross-section Table"},{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t2","@type":"Dataset","description":"The number of events in data and simulations after the fit to data in the Top$\\gamma$ CR, SS$WW\\gamma$ CR, and...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t3","@type":"Dataset","description":"Upper limits on the cross section and derived limits in terms of Yukawa coupling at 95% CL for H\u03b3 production...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t4","@type":"Dataset","description":"The distributions of the invariant mass of the dilepton-photon system after the signal region selection before the fit to data.The...","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t5","@type":"Dataset","description":"The distributions of the invariant mass of the transverse mass of the WW system after the signal region selection before...","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.144361.v2/t6","@type":"Dataset","description":"The unrolled two-dimensional mTWW-mll$\\gamma$ distributions with category 0 jet after the fit to data.
