The Vector and Axial-Vector Susceptibilities and Effective Degrees of Freedom in the Vector Manifestation
The question as to what the relevant degrees of freedom are at the thermal chiral phase transition is addressed in terms of the “vector manifestation (VM)” of chiral symmetry à la Harada and Yamawaki. We find that both the vector susceptibility χV and the axial-vector susceptibility χA at the chiral transition require other degrees of freedom than pions in the chiral limit. The possible candida...
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 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 کاملOn the neutrino vector and axial vector charge radius
A Majorana neutrino is characterized by just one flavor diagonal electromagnetic form factor: the anapole moment, that in the static limit corresponds to the axial vector charge radius 〈 r2 A 〉 . As is the case for the vector charge radius of a Dirac neutrino, proving that this quantity is a well defined physical quantity is non trivial. I will first describe briefly the origin of the long stan...
متن کاملaxial-vector mesons
A previous model where the low-lying axial-vector mesons are dynamically generated, implementing unitarity in coupled channels in the vector-pseudoscalar (V P ) meson interaction, is applied to evaluate the decay widths of the a1(1260) and b1(1235) axial-vector mesons into πγ. Unlike the case of the a1, the b1 radiative decay is systematically underestimated at tree level. In this work we evalu...
