Precision on the top mass

Abstract

In this talk I will focus on theoretical issues related to high precision determinations of the top mass. Several mass definitions are reviewed and their respective advantages and disadvantages are discussed. Precision determinations of the top mass will require a short-distance mass definition. I will summarise current work in this direction.
