Bottom Quark Mass with Calibrated Uncertainty
Abstract
We determine the bottom quark mass mb from QCD sum rules of moments of the vector current correlator calculated in perturbative QCD to O (αs3). Our approach is based on the mutual consistency across a set of moments where experimental data are required for the resonance contributions only. Additional experimental information from the continuum region can then be used for stability tests and to assess the theoretical uncertainty. We find mb(mb) = (4180.2 7.9) MeV for αs(MZ) = 0.1182.
