Measurement of the Higgs boson fiducial and differential cross sections in the 4\ell decay channel at 13 TeV with the ATLAS detector

This poster presents a measurement of the inclusive and differential fiducial cross sections of Higgs-boson production in the four leptons (electrons or muons) final state. The data sample, collected by the ATLAS experiment in 2015 and 2016, corresponds to an integrated luminosity of \SI{36.1}{\per\femto\barn} of proton-proton collisions produced at the Large Hadron Collider at a centre-of-mass energy of \SI{13}{\TeV}. The inclusive fiducial cross section has been measured to be in agreement with the Standard Model (SM) prediction. Moreover, several differential fiducial cross sections have been measured for observables sensitive to the Higgs-boson production and decay. Good agreement has been found between data and SM predictions.
