DESCRIPTION:Paolo Nason (INFN\, Milan-Bicocca)\nThe abundant production of
  top pairs at the LHC has provided an opportunity for accurate top mass m
 easurements. The quoted errors of the LHC experimental collaborations hav
 e reached values near 500 MeV\, to be halved in the future according to p
 resent projections for the High Luminosity. Unfortunately\, several theor
 etical issues have clouded the interpretation of these results. This has 
 led to a number of alternative proposals for top mass measurement strateg
 ies\, but has also left the most precise results in a sort of "limbo"\, w
 ith the hope that some theoretical work may clarify their meaning in the 
 future. In this talk I will discuss the present status of top mass measur
 ement issues\, and I will present some recent work\, based upon the physi
 cs of infrared renormalons\, aimed at clarifying at least some aspects of
  the problem.
