Measurement of Higgs production cross sections in the four lepton channel at 13 TeV with the ATLAS detector

Abstract

The proton$-$proton collision data were produced at the Large Hadron Collider at a centre-of-mass energy of 13~TeV~and recorded by the ATLAS detector from 2015 to 2017, with an integrated luminosity of 79.8 fb$^{-1}$. In this talk, I will cover the measurement of production mode cross sections of the Higgs boson production under the Simplified template cross sections(STXS) in proton-proton collisions in the $H \to ZZ^{*} \to 4\ell$ decay channel. I will talk about the physical motivation, analysis design, some techniques and result. The measurements are in agreement with the Standard Model prediction
