Abstract
Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and system kinematic observables using proton-proton collisions at a center-of-mass energy of . The data set corresponds to an integrated luminosity of , recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Events with two large-radius jets in the final state, one with transverse momentum and a second with , are used for the measurement. The top-quark candidates are separated from the multijet background using jet substructure information and association with a -tagged jet. The measured spectra are corrected for detector effects to a particle-level fiducial phase space and a parton-level limited phase space, and are compared to several Monte Carlo simulations by means of calculated values. The cross-section for production in the fiducial phase-space region is , to be compared to the theoretical prediction of .
