We reexamine the problem of simultaneously describing in a consistent way all radiative and leptonic decays light mesons $(\stackrel{\ensuremath{\rightarrow}}{V}P\ensuremath{\gamma},$ $\stackrel{\ensuremath{\rightarrow}}{P}V\ensuremath{\gamma},$ $\stackrel{\ensuremath{\rightarrow}}{P}\ensuremath{\gamma}\ensuremath{\gamma},$ $\stackrel{\ensuremath{\rightarrow}}{V}{e}^{+}{e}^{\ensuremath{-}})$. For this purpose, we rely on hidden local symmetry model both its anomalous non-anomalous sectors....
We determine the magnitude, phase, and $s$ dependence of $\ensuremath{\rho}$-$\ensuremath{\omega}$ ``mixing'' in pion form factor timelike region through fits to ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ data. The associated systematic errors these quantities, arising from functional used fit $\ensuremath{\rho}$ resonance, are small. mass width, however, larger than previously estimated.
The extraction of Cabibbo-Kobayashi-Maskawa matrix element information from hadronic $B$ decays generally suffers discrete ambiguities, hampering the diagnosis physics beyond standard model. We show that a measurement rate asymmetry, which is $\mathrm{CP}$ violating, in...
Abstract Access to previous results is of paramount importance in the scientific process. Recent progress information management focuses on building e‐infrastructures for optimization research workflow, through both policy‐driven and user‐pulled dynamics. For decades, High Energy Physics (HEP) has pioneered innovative solutions field dissemination. In light a transforming environment, it important assess current usage resources by researchers HEP provides unique test bed this assessment. A...
We study the various existing implementations of SU(3) breaking in hidden local symmetry model for low energy hadronic sector following a mechanism originally proposed by Bando, Kugo and Yamawaki (BKY). pay particular attention to Hermiticity current conservation. Following this, we present new method including effects which preserves BKY mass relation among vector mesons. Symmetry (SB) necessarily requires transformation pseudoscalar fields, which, BKY, refer as field renormalization....
The topic of ρ – ω mixing has received renewed interest in recent years and been studied using a variety modern techniques. A brief history the subject is presented before summarising developments field. present status our understanding discussed.
We discuss the properties of vector mesons, in particular ${\ensuremath{\rho}}^{0},$ context hidden local symmetry (HLS) model. This provides a unified framework to study several aspects low energy QCD sector. First, we show that HLS model physical photon is massless, without requiring off field diagonalization. then demonstrate equivalence and two existing representations meson dominance, VMD1 VMD2, at both tree level one loop order. Finally $S$ matrix pole position shown provide process...
We extract the G-parity-violating branching ratio $B(\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\omega}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})$ from effective ${\ensuremath{\rho}}^{0}$-$\ensuremath{\omega}$ mixing matrix element ${\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\Pi}}}_{\ensuremath{\rho}\ensuremath{\omega}}(s),$ determined ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ data.
