PPT-Top mass measurement

with ATLAS A I Etienvre for the ATLAS Collaboration Introduction Motivations for a precise top quark mass measurement EW precision observables depend on the value of the top mass. 2 lesson plan Measure using conventional units measure quantities less than 1 kilogram in grams By the cupful Students measure and compare the mass of cupfuls of different materials Students estimate first by hefting and then measure the cupfuls to f M. easurements . at .
