Study of the associated production of the Higgs boson with a top quark pair in a boosted regime in the ATLAS experiment at LHC.

The measurements of the $pp \to t\bar{t}H+ X$ signal strength ($\mu = \sigma_{obs}/ \sigma_{t\bar{t}H (SM)}$ ) and its upper limit at a center-of-mass energy of $pp$ collision of 13 TeV are presented in this thesis. The $pp$ data collected with the ATLAS detector in 2015 and 2016, corresponding to a...
