Abstract
Using recent values of αs, the gluon condensates ãαsG2ã and ãg3fabcG3ã and the new data on the Ï/Ï-families, we update our determinations of the MSâ¾ running quark masses mâ¾c,b(mâ¾c,b) from the SVZ-moments Mn(Q2) and their ratios [1], [2] by including higher order perturbative (PT) corrections, non-perturbative (NPT) terms up to dimension d=8 and using the degree n-stability criteria of the (ratios of) moments. Optimal results from different (ratios of) moments converge to the accurate mean values: mâ¾c(mâ¾c)=1264(6)MeV and mâ¾b(mâ¾b)=4188(8)MeV in Table 4, which improve and confirm our previous findings [1], [2] and the recent ones from Laplace sum rules [3]. Comments on some other determinations of mâ¾c(mâ¾c) and ãαsG2ã from the SVZ-(ratios of) moments in the vector channel are given in Section 5.
