Description

Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and t$\bar{\text{t}}$ system kinematic observables using proton-proton collisions at a center-of-mass energy of $\sqrt{s}$=13  TeV. Events with hadronically decaying pairs of top quarks are selected by requiring two large-radius jets in the final state, one with transverse momentum p$_{\text{T}}$>500  GeV and a second with p$_{\text{T}}$>350  GeV and separated from background using top-tagging and b-tagging. This measurement is performed using the full Run 2 dataset corresponding to an integrated luminosity of 139 fb$^{-1}$.
