Renormalon effects in top-mass sensitive observables

Abstract

A precise determination of the top mass is one of the key goals of the LHC and future colliders. Since power corrections are now becoming a source of worry for top-mass measurements, in these proceedings I discuss the impact of linear infrared renormalons, which plague the definition of the top pole-mass $m$, on observables expressed in terms of $m$ and in terms of a short-distance mass.
