Description
The top quark is the most massive elementary particle in the Standard Model, playing an important role in this theory and many of its extensions. Its mass is a fundamental parameter affecting many precision measurements and consistency tests of the Standard Model.
This contribution reviews recent top-quark mass measurements performed by the ATLAS experiment. These include determinations based on comparisons of differential cross-section measurements with first-principles theoretical calculations, as well as direct measurements in which the mass is extracted through comparisons with Monte Carlo simulation templates.
