Abstract:
We consider recent theoretical and experimental improvements in determining charm- and bottom-quark masses. We present a new, improved evaluation of the contribution of the gluon condensate ⟨αsG2/π⟩ to the charm mass determination and a detailed study of potential uncertainties in the continuum cross section for b¯b production, together with a study of the parametric uncertainty from the αs-dependence of our results. The final results, mc(3\,GeV)=986(13)\,MeV and mb(mb)=4163(16)\,MeV, together with the closely related lattice determination mc(3\,GeV)=986(6)\,MeV, currently represent the most precise determinations of these two fundamental standard-model parameters. We critically analyze the theoretical and experimental uncertainties.
Keywords:
QCD sum rules, heavy quark mass, vacuum polarization.
