Vector Meson Dominance, Axial Anomaly and the Thermal behavior of gρωπ(T)
By using a thermal Finite Energy QCD Sum Rule, we are able to establish the temperature dependence of the gωρπ(T) strong coupling. It turns out that this coupling decreases as a function of temperature, vanishing at the critical temperature. This corresponds to a possible deconfining phenomenological signal. This result, together with the Vector Meson Dominance (VMD) expression for the amplitud...
متن کاملAxial anomaly , vector meson dominance and π 0 → γγ at finite temperature
A thermal Finite Energy QCD Sum Rule is used to determine the temperature behaviour of the ωρπ strong coupling. This coupling decreases with increasing T and vanishes at the critical temperature, a likely signal for quark deconfinement. This is then used in the Vector Meson Dominance (VMD) expression for the π0 → γγ amplitude, which is also found to vanish at the critical temperature, as expect...
متن کاملVector meson dominance and the ρ meson
We discuss the properties of vector mesons, in particular the ρ 0 , in the context of the Hidden Local Symmetry (HLS) model. This provides a unified framework to study several aspects of the low energy QCD sector. Firstly, we show that in the HLS model the physical photon is massless, without requiring off field diagonalization. We then demonstrate the equivalence of HLS and the two existing re...
متن کاملThe Axial Vector Current Anomaly and the Meson Decay Constants for the Improved Lattice Fermion Action
We discuss the anomaly in the axial vector current for the improved fermion action on the lattice. A detailed discussion of the fermion regularization dependence of the anomaly is given and it is shown that for finite lattice spacing the improved fermion action gives a more reasonable value for the anomaly contribution at finite quark mass than the Wilson action. We also present some results on...
متن کاملVector Meson Dominance and Rho-Omega Mixing
The scale of a phenomenologically successful charge-symmetry-violating nucleon-nucleon interaction, that attributed to meson exchange with a ∆I = 1 rho-omega transition, is set by the Coleman-Glashow SU(2) breaking tadpole mechanism. A single tadpole scale has been obtained from symmetry arguments, electromagnetic meson and baryon measured mass splittings, and the observed isospin violating (∆I...
