ATLAS measurements of jets and heavy flavor produced in association with W and Z bosons

The production of light and heavy flavors jets in association with a W or Z boson at the LHC represent important processes with which to study QCD in a multi-scale environment. Unprecedented precision is achieved in measurements of differential cross sections and multiplicities with the ATLAS detector, and comparisons are made to state-of-the-art high NLO QCD calculations of high-multiplicity final states. W/Z+jets events involving jets containing b-hadrons are also identified, and small tensions with theoretical predictions discussed.
