Standard Model measurements involving the production of 𝑍 and 𝑊 bosons in association with jets
is an important part of the ATLAS physics program at the LHC. The measurement of integrated
and differential production cross sections constitutes a powerful tool to test our understanding of
the Monte Carlo generators and of the hadronization processes, as well as a way to explore the
initial state of the proton-proton interaction. In these proceedings, a recent ATLAS measurement
of the associated production of the 𝑍-boson with a high-𝑝T (boosted) jet is described, both flavor inclusive
and with 𝑏-quark tagging of the jet. The measurement is performed using proton-proton
collisions at √𝑠 = 13 TeV at the LHC with an integrated luminosity of 36 fb−1 acquired by
the ATLAS detector during Run-2. A discussion of the results and their complementarity with
a previous measurement of the associated production of the 𝑍-boson with 𝑏-tagged jets in the
resolved regime is given. Particular emphasis is devoted to the discussion of the modeling issues
affecting the flavor-inclusive selection and of the ability of the experimental results obtained with
the 𝑏-tag selection to discriminate among models implementing different flavor-number schemes
to describe the initial state of the interaction.
