Abstract | This Letter reports the observation of 𝑊𝑍𝛾 production and a measurement of its cross section using 140.1±1.2 fb−1 of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The 𝑊𝑍𝛾 production cross section, with both the 𝑊 and 𝑍 bosons decaying leptonically, 𝑝𝑝→𝑊𝑍𝛾→ℓ′±𝜈ℓ+ℓ−𝛾 (ℓ(′)=𝑒, 𝜇), is measured in a fiducial phase-space region defined such that the leptons and the photon have high transverse momentum and the photon is isolated. The cross section is found to be 2.01±0.30(stat)±0.16(syst) fb. The corresponding standard model predicted cross section calculated at next-to-leading order in perturbative quantum chromodynamics and at leading order in the electroweak coupling constant is 1.50±0.06 fb. The observed significance of the 𝑊𝑍𝛾 signal is 6.3𝜎, compared with an expected significance of 5.0𝜎. |
