Measurements of observables sensitive to colour reconnection in tt¯ events with the ATLAS detector at √s= 13 TeV

Popis výsledku v původním jazyce

A measurement of observables sensitive to effects of colour reconnection in top-quark pair-production events is presented using 139 fb−1fb−1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the LHC. Events are selected by requiring exactly one isolated electron and one isolated muon with opposite charge and two or three jets, where exactly two jets are required to be b-tagged. For the selected events, measurements are presented for the charged-particle multiplicity, the scalar sum of the transverse momenta of the charged particles, and the same scalar sum in bins of charged-particle multiplicity. These observables are unfolded to the stable-particle level, thereby correcting for migration effects due to finite detector resolution, acceptance and efficiency effects.
