Abstract
Inclusive and differential fiducial cross sections

of the Higgs boson are measured in the H → Z Z∗ → 4

( = e, μ) decay channel. The results are based on protonproton collision data produced at the Large Hadron Collider

at a centre-of-mass energy of 13 TeV and recorded by the

ATLAS detector from 2015 to 2018, equivalent to an integrated luminosity of 139 fb−1. The inclusive fiducial cross

section for the H → Z Z∗ → 4 process is measured to be

σfid = 3.28 ± 0.32 fb, in agreement with the Standard Model

prediction of σfid,SM = 3.41 ± 0.18 fb. Differential fiducial cross sections are measured for a variety of observables

which are sensitive to the production and decay of the Higgs

boson. All measurements are in agreement with the Standard

Model predictions. The results are used to constrain anomalous Higgs boson interactions with Standard Model particles.
