Weinberg like sum rules revisited Sergey
نویسنده
چکیده
The generalized Weinberg sum rules containing the difference of isovector vector and axial-vector spectral functions saturated by both finite and infinite number of narrow resonances are considered. We give a historical survey and summarize the status of these sum rules analyzing their overall agreement with phenomenological Lagrangians, lowenergy relations, parity doubling, hadron string models, and experimental data.

Weinberg like sum rules revisited
The generalized Weinberg sum rules containing the difference of isovector vector and axial-vector spectral functions saturated by both finite and infinite number of narrow resonances are considered. We summarize the status of these sum rules and analyze their overall agreement with phenomenological Lagrangians, low-energy relations, parity doubling, hadron string models, and experimental data.
متن کاملFinite energy chiral sum rules in QCD
The saturation of QCD chiral sum rules of the Weinberg-type is analyzed using ALEPH and OPAL experimental data on the difference between vector and axial-vector correlators (V-A). The sum rules exhibit poor saturation up to current energies below the tau-lepton mass. A remarkable improvement is achieved by introducing integral kernels that vanish at the upper limit of integration. The method is...
متن کاملCalculation of a weak nonleptonic matrix element using “Weinberg” sum rules
There is a “toy” weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, ρV (s)− ρA(s). I review our recent evaluation of these spectral functions, the study of four “Weinberg” sum rules and the calculation of this matrix element. [Talk presented at the XXVIII International Conference on High Energy Physics, ICHEP94, Glasgow, Aug. 1994, to ...
متن کاملNeural network parametrization of spectral functions from hadronic tau decays and determination of QCD vacuum condensates
The spectral function ρV −A(s) is determined from ALEPH and OPAL data on hadronic tau decays using a neural network parametrization trained to retain the full experimental information on errors, their correlations and chiral sum rules: the DMO sum rule, the first and second Weinberg sum rules and the electromagnetic mass splitting of the pion sum rule. Nonperturbative QCD vacuum condensates can...
متن کاملDropping Ρ and a 1 Meson Masses at the Chiral Phase Transition in the Generalized Hidden Local Symmetry *
In this contribution to the proceedings, we present our recent analysis on the chiral symmetry restoration in the generalized hidden local symmetry (GHLS) which incorporates the rho meson, A1 meson and the pion consistently with the chiral symmetry of QCD. It is shown that a set of parameter relations, which ensures the first and second Weinberg sum rules, is invariant under the renormalization...
