Measurement of the ttH production cross-section in multi-leptonic final states in pp collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector

The Yukawa coupling of the Higgs boson to the top quark is a key parameter of the Standard Model. This coupling can be directly measured from the process of gg/qq -> ttH. And the multilepton channel is the most sensitive channel in this process. A search for ttH production in multilepton final states has been performed with an integrated luminosity of 80 fb-1 at a centre-of-mass energy of 13 TeV. Results and progress for the inclusive and differential cross section will be presented.
