A fiducial cross section for W gamma production in proton-proton collisions at 13 TeV center-of-mass energy was measured using data collected with the CMS detector at the LHC, and compared with theoretical expectations. Additionally, 95% confidence level intervals were reported for anomalous triple-gauge couplings within the effective field theory framework.
A fiducial cross section for W gamma production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb(-1) of data collected using the CMS detector at the LHC. The W -> e nu and mu nu decay modes are used in a maximum-likelihood fit to the lepton-photon invariant mass distribution to extract the combined cross section. The measured cross section is compared with theoretical expectations at next-to-leading order in quantum chromodynamics. In addition, 95% confidence level intervals are reported for anomalous triple-gauge couplings within the framework of effective field theory.
