NJL interaction derived from QCD: vector and axial-vector mesons
In previous works effective non-local SU(2) × SU(2) NJL model was derived in the framework of the fundamental QCD. All the parameters of the model are expressed through QCD parameters: current light quark mass m0 and average non-perturbative αs. The results for scalar and pseudo-scalar mesons are in satisfactory agreement to existing data. In the present work the same model without introduction...
متن کاملNote on finite temperature sum rules for vector and axial - vector spectral functions ∗
An updated analysis of vector and axial-vector spectral functions is presented. The resonant contributions to the spectral integrals are shown to be expressible as multiples of 4π 2 f 2 π , encoding the scale of spontaneous chiral symmetry breaking in QCD. Up to order T 2 this behavior carries over to the case of finite temperature.
متن کاملMeasurement of the Strong Coupling Constant αs and the Vector and Axial-Vector Spectral Functions in Hadronic Tau Decays
The spectral functions of the vector current and the axial-vector current have been measured in hadronic τ decays using the OPAL detector at LEP. Within the framework of the Operator Product Expansion a simultaneous determination of the strong coupling constant αs, the non-perturbative operators of dimension 6 and 8 and of the gluon condensate has been performed. Different perturbative descript...
متن کاملSymmetries for Vector and Axial - Vector Mesons ∗
We discuss the possible symmetries of the effective lagrangian describing interacting pseudoscalar-, vector-, and axial-vector mesons. Specific choices of the parameters give rise to an [SU(2) ⊗ SU(2)] symmetry. This symmetry can be obtained either á la Georgi, with all states in the spectrum remaining massless, or in a new realization, implying decoupling of the pseudoscalar bosons from degene...
متن کاملBaryon-number-induced Chern-Simons couplings of vector and axial-vector mesons in holographic QCD.
We show that holographic models of QCD predict the presence of a Chern-Simons coupling between vector and axial-vector mesons at finite baryon density. In the Anti de Sitter/Conformal Field Theory dictionary, the coefficient of this coupling is proportional to the baryon number density and is fixed uniquely in the five-dimensional holographic dual by anomalies in the flavor currents. For the li...
