Measurements of the Top Quark Mass at ATLAS and CMS

Abstract

We present recent measurements of the top quark mass by the ATLAS and CMS experiments in the $\mathrm{t}\overline{\mathrm{t}}$ lepton+jets, all-hadronic, and dilepton channels. In addition, we present a measurement using a topology enriched in t-channel single top events. The analyses include observables whose sensitivity to the top mass is calibrated using Monte Carlo simulation before they are utilized to extract the value of $\mathrm{m}_{\mathrm{t}}$ in data. The measurements outlined here enter into recent combinations by ATLAS and CMS that yield a sub-GeV precision on the top mass.
