Description
The top quark mass is a fundamental parameter of the Standard Model, entering in the precision tests even before the Higgs discovery and playing a crucial role in any assumption on the stability of the electroweak vacuum. Therefore, determining it with the highest precision and having under control all sources of errors will be of paramount importance. I will investigate the uncertainties in the top mass extraction due to bottom-quark fragmentation in top decays, in the context of both Monte Carlo generators and resummed calculations. In particular, I will discuss the interpretation of the measured mass as a pole mass and the sources of both perturbative and non-perturbative uncertainties.
