Measurement of inclusive and differential cross sections in the H → ZZ* → 4ℓ decay channel in pp collisions at √s = 13 TeV with the ATLAS detector

Inclusive and differential fiducial cross sections of Higgs boson production in proton-proton collisions are measured in the H → ZZ* → 4ℓ decay channel. The protonproton collision data were produced at the Large Hadron Collider at a centre-of-mass energy of 13TeV and recorded by the ATLAS detector i...
