      abstract     = {The top quark is the most massive elementary particle
                      known. Its mass,mt, is a fundamental parameter of the
                      Standard Model, and its value needs to be determined
                      experimentally. However, direct top quark mass measurements
                      suffer from ambiguities in their interpretation because of
                      nonperturbative effects.In this work, the pole mass of the
                      top quark is extracted from a precise measurement of the
                      distribution in ρ, in events where the tt system is
                      produced in association with at least one additional jet.
                      The variable ρ is defined as the inverse of the invariant
                      mass of the tt+jet system. This observable has been chosen
                      due to strongest sensitivity to mt at the threshold of the
                      tt+jet production. The analysis is performed using
                      proton-proton collision data collected by the CMS experiment
                      in 2016-2018 with √s=13 TeV, corresponding to a total
                      integrated luminosity of 138 fb−1. Events with two
                      opposite-sign leptons in the final state are analyzed and
                      the cross section is measured at the parton level using a
                      likelihood unfolding method.},
