Abstract
A measurement of the top-quark pole mass mtpolemtpole is presented in tt‾tt events with an additional jet, tt‾tt + 1-jet, produced in pp collisions at s=13s =13 TeV. The data sample, recorded with the ATLAS experiment during Run 2 of the LHC, corresponds to an integrated luminosity of 140 fb−1−1. Events with one electron and one muon of opposite electric charge in the final state are selected to measure the tt‾tt + 1-jet differential cross-section as a function of the inverse of the invariant mass of the tt‾tt + 1-jet system. Iterative Bayesian Unfolding is used to correct the data to enable comparison with fixed-order calculations at next-to-leading-order accuracy in the strong coupling. The process pp→tt‾j(2→3)pp→ttj(2→3), where top quarks are taken as stable particles, and the process pp→bb‾l+νl−ν‾j(2→7)pp→bbl+νl−νj(2→7), which includes top-quark decays to the dilepton final state and off-shell effects, are considered. The top-quark mass is extracted using a χ22 fit of the unfolded normalized differential cross-section distribution. The results obtained with the 2 → 3 and 2 → 7 calculations are compatible within theoretical uncertainties, providing an important consistency check. The more precise determination is obtained for the 2 → 3 measurement: mtpole=170.7±0.3(stat.)±1.4(syst.)±0.3(scale)±0.2(PDF⊕αS)mtpole=170.7±0.3(stat.)±1.4(syst.)±0.3(scale)±0.2(PDF⊕αS) GeV, which is in good agreement with other top-quark mass results.
