Inclusive and differential fiducial cross sections of the Higgs boson are measured in the H ightarrow ZZ^{*} ightarrow 4ellH→ZZ ∗ →4ℓ (ell = e,muℓ=e,μ) decay channel. The results are based on proton−proton 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 hbox {fb}^{-1}. The inclusive fiducial cross section for the H ightarrow ZZ^{*} ightarrow 4ellH→ZZ ∗ →4ℓ process is measured to be sigma _mathrm {fid} = 3.28 pm 0.32σ fid ​ =3.28±0.32 fb, in agreement with the Standard Model prediction of sigma _mathrm {fid, SM} = 3.41 pm 0.18σ fid,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.
