abstract = {Differential cross-section measurements of $Z\gamma$
production in association with hadronic jets are presented,
using the full Run-2 proton-proton dataset of 139 fb$^{-1}$
produced by the LHC at $\sqrt{s}$ = 13 TeV and collected by
the ATLAS detector. Distributions are measured using events
in which the $Z$ boson decays leptonically and the photon is
predominantly radiated off the initial state quarks. Both
one- and two-dimensional observables are considered,
including observables sensitive to the hard scatter in the
event and observable which probe additional soft and
collinear radiation. The measurements are compared to
different Standard Model predictions, both parton-shower
Monte-Carlo simulation and fixed-order QCD calculations.
General good agreement is observed between data and
state-of-the art theoretical next-to-next-leading-order
predictions $\mathbf{MATRIX/MiNNLO}$$_{PS}$ and with
$\mathbf{M{\small{AD}}G\small{RAPH}}5$_a$\mathbf{MC@NLO}$
and $S\small{HERPA}$ multilegnext-to-leading order
generators.},
