DESCRIPTION:\n    The currently most precise measurements of the top quark
  mass are obtained from kinematic reconstruction obtained at hadron collid
 ers. The observables designed to make these measurements cannot be calcula
 ted using analytic methods in QCD and therefore rely on multipurpose Monte
 -Carlo event generators. As a consequence\, the interpretation of the meas
 ured top quark masses is theoretically difficult and still an open issue. 
 In my talk I explain the theoretical issues inherent to this problem and I
  show some preliminary results from a MC study which illustrates that the 
 shower cut plays an important role. At this point it is not yet fully unde
 rstood\, up to a conceptual upper bound\, how large the uncertainty is whe
 n one interprets the result as measurements of the pole mass. I then expla
 in one approach to shed some light on the interpretation problem using the
  concept of MC calibration with top mass sensitive observables which can b
 e computed systematically at hadron level using analytic methods for boost
 ed top quarks at the LHC.\n\nhttps://indico.ific.uv.es/event/3213/
