The analysis is performed using protonproton collisions at root s = 13 TeV with the CMS detector at the LHC and corresponding to an integrated luminosity of 138 fb(-1). The selection is optimized for top quarks produced with large Lorentz boosts, resulting in nonisolated leptons and overlapping jets. The top quark charge asymmetry is measured for events with a t (t) over bar invariant mass larger than 750 GeV and corrected for detector and acceptance effects using a binned maximum likelihood fit. The measured top quark charge asymmetry of (0.42(-0.69)(+0.64))% is in good agreement with the standard model prediction at next-to-next-to-leading order in quantum chromodynamic perturbation theory with next-to-leading-order electroweak corrections. The result is also presented for two invariant mass ranges, 750-900 and >900 GeV. (c) 2023 The Author(s). Published by Elsevier B.V.
