Measurements of the top quark mass using the ATLAS detector at the LHC

The latest measurements of the top quark mass using the ATLAS experiment are presented. A measurement based on a multi-dimensional template fit that can constrain the uncertainties on the energy measurements of jets is presented and combined with measurements using dilepton and all-hadronic events....

description The latest measurements of the top quark mass using the ATLAS experiment are presented. A measurement based on a multi-dimensional template fit that can constrain the uncertainties on the energy measurements of jets is presented and combined with measurements using dilepton and all-hadronic events. A measurement of the pole mass is performed using the normalised differential cross section of top-quark pair production in association with an energetic jet in the lepton+jets final state unfolded to parton level. A comparison between the experimental distribution and the theoretical prediction allows the top-quark mass to be extracted in the two schemes.
