On the dominance of non-exotic meson-meson scattering by s-channel qqbar confinement states and the classification of the scalar mesons
Eef van Beveren, George Rupp
Non-exotic scalar-meson resonances in S-wave meson-meson scattering are studied in the light of a unitarised Schroedinger model. The resulting poles in the scattering matrices, by…
Identifying the quark content of the isoscalar scalar mesons f_0(980), f_0(1370), and f_0(1500) from weak and electromagnetic processes
Frieder Kleefeld, Eef van Beveren, George Rupp +1
The assignments of the isoscalar scalar mesons f0(980), f0(1370), and f0(1500) in terms of their qqbar substructure is still a matter of heated dispute. Here we employ the weak and…
Modified Breit-Wigner formula for mesonic resonances describing OZI decays of confined states and the light scalar mesons
Eef van Beveren, George Rupp
A general expression resembling Breit-Wigner formulae is derived for the description of resonances which appear in meson-meson scattering. Starting point is a unitarised meson mode…
Comment on Intrinsic and dynamically generated scalar meson states
George Rupp, Eef van Beveren, Michael D. Scadron
The scalar-meson assignments of Shakin and Wang in a generalized Nambu--Jona-Lasinio model are contradicted by recent experimental information. Also the strict distinction made by…
The pionic width of the meson within a well-defined, unitary quantum field theory of (anti-)particles and (anti-)holes
Frieder Kleefeld, Eef van Beveren, George Rupp
We investigate the indirect generation of the partial width of the meson with respect to the reaction within the context of a ``Unitary E…
