We study the two photon decay of neutral scalars below 1.5 GeV in the context of a recently proposed chiral model for bar{q}q and bar{q}bar{q}qq states. We find good agreement with experimental results for the a_{0}(980)->gamma gamma. Our calculations for f_{0}(980)->gamma gamma shows that further work is necessary in order to understand the structure of this meson. The model predicts Gamma(a_{0}(1450)->gamma gamma)=0.16+/-0.10KeV, Gamma(sigma->gamma gamma)=0.47+/-0.66 KeV, Gamma(f(1370)->gamma…

ρ ρ interaction in the hidden gauge formalism and the f 0 ( 1370 ) and f 2 ( 1270 ) resonances
We have studied the interaction of vector mesons within the hidden gauge formalism and applied it to the particular case of the $\ensuremath{\rho}\ensuremath{\rho}$ interaction. We find a strong
Two photons into π0π0
AbstractWe perform a theoretical study based on dispersion relations of the reaction γγ → π0π0 emphasizing the low-energy region. We discuss how the ƒ0(980) signal emerges in γγ → ππ within the
Complex Meson Spectroscopy
We do meson spectroscopy by studying the behavior of S‐matrix poles in the complex‐energy plane, as a function of the coupling strength for 3P0 quark‐pair creation. Thereto, a general formula for
Radiative open charm decay of the Y(3940) , Z(3930) , X(4160) resonances
We determine the radiative decay amplitudes for the decay into D* and $ \bar{{D}}$$ \gamma$ , or D*s and $ \bar{{D}}_{s}^{}$$ \gamma$ of some of the charmonium-like states classified as X , Y , Z


Determining the Gluonic Content of Isoscalar Mesons
We develop tools to determine the gluonic content of a resonance of known mass, width, and J{sup PC} from its branching fraction in radiative quarkonium decays and production cross section in
Determination of radiative widths of scalar mesons from experimental results on
Abstract. The scalar mesons in the 1 GeV region constitute the Higgs sector of the strong interactions. They are responsible for the masses of all light flavour hadrons. However, the composition of
A collective treatment of the I=0 scalar mesons below 2 GeV [σ(550), f0(980), f0(1370), f0(1500) and f0(1710)] in a nonlinear chiral Lagrangian framework that is constrained by the mass and the
Understanding the scalar meson $$q\bar q$$ nonet
It is shown that one can fit the available data on thea o(980),f o(1300) andK o * (1430) mesons as a distorted 0++ $$q\bar q$$ nonet using very few (5–6) parameters and an improved version
Spontaneous breakdown and the scalar nonet
In the context of the QCD quark model and on the basis of dynamical Bethe-Salpeter ladder graphs, we suggest that (i) the existence of the scalar q-barq hadron multiplet, like the pseudoscalar q-barq
Vector-meson-dominance model for radiative decays involving light scalar mesons.
We study a vector-dominance model which predicts quite a large number of currently interesting decay amplitudes of the types S-->gammagamma, V-->Sgamma, and S-->Vgamma, where S and V denote scalar

AbstractA unitarized non-relativistic meson model which is successful for the description of the heavy and light vector and pseudo-scalar mesons yields in its extension to the scalar mesons for the
