Pion Polarisability and Hadronic Tau Decays
V. Kartvelishvili, M. Margvelashvili, G. Shaw
Recent experimental data on tau decays are used to reconstruct the difference in hadronic spectral densities with vector and axial-vector quantum numbers. The saturation of Das-Mat…
On the Flavor Dependence of the Mixed Quark-Gluon Condensate
Ketino Aladashvili, Murman Margvelashvili
The flavour dependence of the mixed quark-gluon condensate is studied through the analysis of correlators of the hybrid current . The flavour symmetry br…
On Instanton Contributions to the tau Hadronic Width
V. Kartvelishvili, M. Margvelashvili
Comparing the results of finite energy and Borel transformed sum rules for the difference of vector and axial vector current correlators we evaluate the instanton contributions to…
Estimating Condensates from the Difference of Tau Branching Fractions
Vakhtang Kartvelishvili, Murman Margvelashvili
The difference of tau partial decay widths into even and odd number of pions may be considered as another important constraint on the hadronic spectral function, in addition to fou…
Determination of QCD Condensates Without Hadronic Spectra
Ketino Aladashvili, Murman Margvelashvili
The bounds on the values of gluon, four-quark and quark-gluon condensates are derived from the requirement of consistency of the sum rules for various correlators of the hybrid cur…
