Measurement of the WZ boson pair production cross section at 13 TeV and confidence intervals on anomalous triple gauge couplings with the ATLAS detector

Abstract : The WZ boson pair production at 13 TeV is measured using the ATLAS detector. Leptonic decays of the W and Z bosons to electrons and muons are considered using 2015 and 2016 data that correspond to a total integrated luminosity of 13.3 fb−1. The differential cross-section as a function of jet multiplicity is also measured along with the charge-dependent W+Z and W−Z cross-sections and their ratio. Also, the integrated fiducial cross-sections ratio, measured at center-of-mass energies of 8 TeV and 13 TeV, is calculated. Finally, limits on anomalous triple gauge couplings are derived.
