Description
The CMS Collaboration has carried out a rich program of top quark mass measurements, providing thorough tests of the internal consistency of the Standard Model. While direct measurements suffer from ambiguities in interpreting the measured parameter, extractions from cross-section measurements provide a solution to this problem with the drawback of being less precise and relying on the picture of a stable top quark. In this talk, we focus on extractions of the top quark mass from the jet mass distribution in fully hadronic decays of boosted top quarks. These have proven to be competitive in precision compared to other measurements and have the potential to be turned into an extraction of a well-defined top quark mass. This measurement complements other top quark mass extractions as it has different uncertainties. We present the current status, explore potential improvements, and provide an outlook for such a measurement at the HL-LHC.
