Vector 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...

Cabibbo–Kobayashi–Maskawa-favored B decays to a scalar meson and a D meson

In this work, we attempt to study the Cabibbo-Kobayashi-Maskawa-favored [Formula: see text] ("S" denoting the scalar meson) decays within the perturbative QCD approach at the leading order and the leading power. Although the light scalar mesons are widely perceived as primarily the four-quark bound states, in practice it is hard for us to make quantitative predictions based on the four-quark pi...

Scalar Meson Photoproduction

The light-quark non-strange scalar mesons a0(980), f0(980), f0(1370), a0(1450), f0(1500) and f0(1710) are of great interest as there is no generally accepted view of their structure which can encompass qqq̄q̄, molecular, qq̄ and glueball states in various combinations. It has been shown previously that the radiative decays of the scalar mesons to ρ and ω are a good probe of their structure and pro...

Light scalar meson spectrum

We discuss the classification of the light scalar mesons with mass below 2 GeV into qq̄ nonets and glueballs. The information on production and decay of these states, in particular recent information on the f0(980), f0(400−1200) (or σ(600)) and f0(1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes ...
