Measurements of Multi-Boson Production at 13TeV using ATLAS

Daniel Lewis (Annecy LAPP)


Measurements of multi-boson processes provide a probe of the EW sector of the SM. The vast integrated luminosity of 139 /fb recorded by the ATLAS experiment during Run 2 of the LHC allows for very precise measurements which can be used as benchmarks to test state-of-the-art theoretical predictions. It also allows for the observation and study of much rarer processes which were unaccessible at previous colliders. The fiducial cross-section measurements for Zy and Zyy production are presented and their impact on testing predictions and constraining new physics effects are discussed.
