Observation of WZ𝛾 production in pp collisions at √s = 13 TeV with the ATLAS detector
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 an...

| 520 | |a This Letter reports the observation of 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 production cross section, with both the and bosons decaying leptonically, →→ℓ′±ℓ+ℓ− (ℓ(′)=, ), 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 signal is 6.3, compared with an expected significance of 5.0. | ||
