Low energy sum rules for pi - pi scattering and threshold parameters.
We derive a set of sum rules for threshold parameters of pion-pion scattering whose dispersion integrals are rapidly convergent and are dominated by Sand P-waves absorptive parts. Stringent constraints on some threshold parameters are obtained. PACS Nos.: 13.75.Lb, 11.55.Hx, 11.10.Cd, 25.80.Dj.

متن کاملLow-energy Compton scattering on the nucleon and sum rules
The Gerasimov-Drell-Hearn and Baldin-Lapidus sum rules are evaluated in a relativistic, unitary, crossing symmetric and gauge-invariant model for photon-induced reactions on the nucleon. The property of analyticity is partially incorporated through a dressing procedure for propagators and vertices. The sum α + β of the electric and magnetic polarisabilities and the forward spin polarisability γ...
متن کاملLow-energy sum rules and large-Nc consistency conditions
The large-Nc consistency conditions for axial vector and isovector magnetic couplings of pions to baryons are discussed from the point of view of lowenergy current-algebra sum rules (Adler-Weisberger, Cabibbo-Radicati). In particular, we show how the result that ratios of axial vector and isovector magnetic coupling constants get corrections only at the order 1/N2 c follows from the Nc-counting...
متن کاملImproved sum rules for light mesons and thermal hadronic threshold
The thermal properties of light vector and scalar mesons are investigated in the framework of QCD sum rules. The phenomenological side of the correlation function can be calculated using either the quark-hadron duality approach or in terms of two-pion continuum contributions. In the quark-hadron duality approach, a free parameter (hadronic threshold) arises in the phenomenological part and it i...
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...
