Description

The top quark mass is one of the fundamental parameters of the Standard Model. The latest ATLAS measurements of the top quark mass are presented. A measurement using lepton+jets events is presented, where a multidimensional template fit is used to constrain the uncertainties on the energy measurements of jets. The measurement is combined with a measurement using dilepton events. In addition, novel measurements aiming to measure the mass in a welldefined scheme are presented. These measurements use precision theoretical QCD calculations for both inclusive ttbar production and ttbar production with an additional jet to extract the top quark mass in the polemass scheme.
