Abstract:
New data for the total cross section in the charm and bottom threshold region are combined with an improved theoretical analysis, which includes recent four-loop calculations, to determine the short distance charm and bottom quark masses. A detailed discussion of the theoretical and experimental uncertainties is presented. The final result for the -masses, GeV and GeV, can be translated into GeV and GeV. This analysis is consistent with but significantly more precise than a similar previous study.- 14.65.Dw
