W/Z + jets and W/Z + heavy flavor production at the LHC

The ATLAS and CMS experiments at the LHC conduct an extensive program to study production of events with a W or Z boson and particle jets. Dedicated studies focus on final states with the jets containing decays of heavy-flavor hadrons (b-tagged jets). The results are obtained using data from proton-proton collisions at sqrt{s}=7 TeV from the LHC at CERN. The set of measurements constitute a stringent test of the perturbative QCD calculations.
