Vector and axial - vector correlators in a chirally symmetric model
We present a chirally symmetric hadronic model for the vector and axial-vector correlators in vacuum. The dominant contributions to these correlators come from intermediate pions, ρ and a 1 mesons which are calculated in one-loop approximation. The resulting spectral functions are compared with the data obtained by the ALEPH collaboration from τ decay. In the vector channel we find good agreeme...
متن کاملVector and Axial - Vector Current Correlators within the Instanton Model of Qcd Vacuum
The pion electric polarizability, α E π ± , the leading order hadronic contribution to the muon anomalous magnetic moment, a hvp(1) µ , and the ratio of the difference to the sum of vector and axial-vector correlators, (V − A)/(V + A), are found within the instanton model of QCD vacuum. The results are compared with phenomenological estimates of these quantities following from the ALEPH and OPA...
متن کاملSemi-leptonic Octet Baryon Weak Axial-Vector Form Factors in the Chiral Constitutent Quark Model
The weak vector and axial-vector form factors have been investigated for the semi-leptonic octet baryon decays in the chiral constituent quark model with configuration mixing (χCQMconfig). The effects of SU(3) symmetry breaking and configuration mixing have also been investigated and the results are not only in good agreement with existing experimental data but also show improvement over other ...
متن کاملHidden Local Symmetry and Chiral Effective Theory for Vector and Axial-vector Mesons
In this paper, we present the full Lagrangian of mesons (pseudoscalars, vectors and axial-vectors) to O(p4) by using the explicit global chiral symmetry and hidden local symmetry in the chiral limit. In this approach, we see that there are many other terms besides the usual eleven terms given in the literature from hidden local symmetry approach. Of particular, there are some terms in our full ...
متن کاملFinite-Size Scaling of Vector and Axial Current Correlators
Using quenched chiral perturbation theory, we compute the long-distance behaviour of twopoint functions of flavour non-singlet axial and vector currents in a finite volume, for small quark masses, and at a fixed gauge-field topology. We also present the corresponding predictions for the unquenched theory at fixed topology. These results can in principle be used to measure the low-energy constan...
