V-A sum rules with D=10 operators
K. N. Zyablyuk
The difference of vector and axial-vector charged current correlators is analyzed by means of QCD sum rules. The contribution of 10-dimensional 4-quark condensates is calculated an…

QCD sum rule analysis of V and A current correlators from tau-decay data
K. N. Zyablyuk
2-point correlators of vector and axial currents, obtained from tau-decay data, are studied within the framework of perturbative QCD and Operator Product Expansion. Various sum rul…
