Measurement of the $t\bar{t}H$ production
J. D. Mellenthin · CERN Document Server (European Organization for Nuclear Research) · 2018
The top quark is the heaviest elementary particle in the Standard Model, and has an expected Yukawa coupling of order unity. The value of this coupling is a key ingredient to unravel the nature of the observed Higgs boson. The only known process which has a direct sensitivity to this coupling is the production of a Higgs boson in association with a top quark-pair ($t\\bar{t}H$). This talk will present an overview of the $\\sqrt{s} = 13\\, \\text{TeV}$ $t\\bar{t}H$ ATLAS analyses leading to the observation of this process.
