Description
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 TeV $t\bar{t}H$ ATLAS analyses leading to the observation of this process.
