We reconsider the extraction of the gluon condensates 〈αsG2〉, 〈g3fabcG3〉 and the MS¯ running quark masses m¯c,b from different Mn(Q2) moments and their ratios by including PT corrections to order αs3, NPT terms up to 〈G4〉 and using stability criteria of the results versus the degree n (number of Q2-derivative). We explicitly show that the spectral part of the lowest moment M1(0) depends strongly (as...
We test the convergence of the QCD exponential sum rules by including PT corrections to order αs3 and the NP contributions up to dimension D=8 condensates. Then, using the ratio of exponential sum rules where the QCD PT series is more convergent, we study the correlation between the gluon condensates 〈αsG2〉 and 〈g3fabcG3〉. From charmonium systems and using the charm quark mass as input, we deduce:...
