Vector Meson Propagator and Baryon Current Conservation
If baryons couple only with ω-mesons, one found the baryon spectral function may be negative. We show this unacceptable result is caused by the kμkν-terms in the ω-meson propagator. Their contribution may not vanish in approximate calculations, though the baryon current conserves. A rule is suggested, by which the calculated baryon spectral function is well behaved. PACS: 21.60.

متن کاملNonlocal anomaly of the axial-vector current for bound states.
We argue that the amplitude does not vanish in the limit of zero quark masses. This represents a new kind of violation of the classical equation of motion for the axial current and should be interpreted as the axial anomaly for bound states. The anomaly emerges in spite of the fact that the one loop integrals are ultraviolet finite as guaranteed b...
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...
متن کاملAxial vector current of exact chiral symmetry on the lattice
We discuss the exact chiral symmetry and its spontaneous breakdown in lattice QCD with the Dirac operators satisfying the GinspargWilson relation. The axial vector current, which turns out to be related to the vector current simply by the insertion of the operator γ5(1−aD), is explicitly constructed in the case of the Neuberger-Dirac operator. We also consider an Euclidean proof of the Nambu-Go...
متن کاملNucleon Form Factors of the Isovector Axial - Vector Current
The theoretical and experimental status of the isovector axial-vector current form factors GA(q 2) and GP (q 2) of the nucleon is reviewed. We also describe a new calculation of these form factors in manifestly Lorentz-invariant chiral perturbation theory (ChPT) with the inclusion of axial-vector mesons as explicit degrees of freedom.
