A fresh look into the heavy quark-mass values
Using the recent {\it world average} \alpha_s(M^2_Z)= 0.118 \pm 0.006, we give the {\it first direct extraction} from the \Psi and \Upsilon data of the values of the {\it running heavy quark masses} within QCD spectral sum rules to two-loops in the \overline {MS}-scheme: \mr_b(M^{PT2}_b) = (4.23~^{+...
