Precise Charm and Bottom quark masses
Abstract
New data for the total cross section sigma(e+e- --> hadrons) 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 MS charm and bottom quark masses. The final result for the MS-masses, mc(3 GeV)=0.986(13) GeV and mb(10 GeV)=3.609(25) GeV is consistent with but significantly more precise than a similar previous study.
