AB  - In this thesis measurements of the t―t pair production at the very high transverse momentum are presented. When a top quark is produced with very high momentum the decay products are collimated in the direction of the quark, and they can be clustered within a single large cone size jet. The decay products of  top quarks with transverse momentum larger than 400 GeV are likely having this boosted configuration. A definition of a particle-level top jet is developed which is independent of the partonic configuration. The measurements are performed with proton-proton collision data collected by the CMS experiment at the LHC, at the center of mass energy of √s=13 TeV and they are presented differentially in the transverse momentum of the top jets and differentially in the azimuthal angle ∆ϕ between the two top-jets. The results are compared to theory predictions provided from different Monte Carlo event generators: i.e Powheg+Pythia8, Powheg+Herwigpp and aMC@NLO+Pythia8.
