Rho-omega Mixing and the Pion Electromagnetic Form-factor

چکیده
The suggestion of momentum dependence in the amplitude for rho-omega mixing has generated concern over related implications for vector meson dominance and the photon-rho coupling. We discuss two established representations of vector meson dominance and show that one of these is completely consistent with such a coupling. We then apply it to a calculation of the pion electromagnetic form-factor. Our analysis leads to a new value for the on-shell rho-omega mixing amplitude of −3800 ± 370 MeV 2 .

Rho - Omega Mixing and the Pion Form Factor in the Time - like Region
We determine the magnitude, phase, and s-dependence of ρ-ω " mixing " in the pion form factor in the time-like region through fits to e + e − → π + π − data. The associated systematic errors in these quantities, arising from the functional form used to fit the ρ resonance, are small. The systematic errors in the ρ mass and width, however, are larger than previously estimated.
متن کاملAnalysis of rho - omega interference in the pion form - factor
The formalism underlying the analysis of e + e − → π + π − in the ρ − ω interference region is carefully revisited. We show that the standard neglect of the pure I = 0 omega, ω I , " direct " coupling to ππ is not valid, and extract those combinations of the direct coupling and ρ-ω mixing allowed by experiment. The latter is shown to be only very weakly constrained by experiment , and we conclu...
متن کاملExtracting the ρ − ω mixing amplitude from the pion form - factor
We reexamine and extend a recent analysis which showed that the ρ−ω mixing amplitude cannot be unambiguously extracted from the pion electromagnetic form-factor in a model independent way. In particular, we focus on the argument that the extraction is sensitive to the presence of any intrinsic ω I → ππ coupling. Our extended analysis confirms the original conclusion, with only minor, quantitati...

متن کاملCvc in Particle Physics
We review the hypothesis of the conserved vector current (CVC) within the Standard Model. In addition to the classic tests, such as pion beta decay and neutrino scattering, we mention recent tests involving LEP data. As well as providing a clear indication that the isovector current is not conserved, rho-omega mixing offers a fascinating opportunity to study CP violation at B-factories and we o...
