Abstract

We review the most recent measurements of the top quark mass using data collected by the CDF experiment at the Tevatron 1.96 TeV ppbar collider. The mass measurements are performed in all main decay modes of the produced ttbar pairs using integrated luminosities up to 2fb-1. In most channels the total uncertainty is dominated by systematic effects, most of which are currently being revised. The precise measurement of the top quark mass is one of the Tevatron's main and long lasting legacies. Besides serving as a benchmark measurement at the LHC collider, it will serve as a consistency check of the Standard Model in case a a neutral CP even Higgs boson is found, either at the Tevatron or at the LHC.
