Relativistic Unitarized Quark/Meson Model in Momentum Space
George Rupp, Eef van Beveren
An outline is given how to formulate a relativistic unitarized constituent quark model of mesons in momentum space, employing harmonic quark confinement. As a first step, the momen…
The light scalar mesons within quark models
Eef van Beveren, George Rupp, Nicholas Petropoulos +1
Low-energy meson-meson scattering data are a powerful testing ground for quark models. Here, we describe the behaviour at threshold of S-wave scattering-matrix singularities. The m…
Meson Form Factors and the Quark-Level Linear Sigma Model
Michael D. Scadron, Frieder Kleefeld, George Rupp +1
The quark-level linear sigma model is employed to compute a variety of electromagnetic and weak observables of light mesons, including pion and kaon form factors and charge radii,…
Behaviour of S-Wave poles Near Threshold and the Scalar Meson Nonet Below 1 GeV
Eef van Beveren, George Rupp
We describe the behaviour at threshold of S-wave poles of the scattering matrix within a four-parameter model for non-exotic meson-meson scattering. This model accommodates all non…
Remarks on the f_0(400-1200) scalar meson as the dynamically generated chiral partner of the pion
Eef van Beveren, Frieder Kleefeld, George Rupp +1
The quark-level linear sigma model is revisited, in particular concerning the identification of the f_0(400-1200) (or σ(600)) scalar meson as the chiral partner of the pion. We dem…
Scalar Mesons within a model for all non-exotic mesons
Eef van Beveren, George Rupp
We describe a four-parameter model for non-exotic meson-meson scattering, which accommodates all non-exotic mesons, hence also the light scalar mesons, as resonances and bound stat…
