Deducing the string-breaking distance in strong production processes
Eef van Beveren, George Rupp
We show that the string-breaking distance can be read from meson-production data, by employing a previously derived expression for the production amplitude. Accordingly, we find th…
Why the Pennington-Wilson expansion with real coefficients is of little use in the analysis of production processes
Eef van Beveren, George Rupp
We critically analyse and comment on the claims of M. R. Pennington and D. J. Wilson [arxiv:0711.3521]. Although we generally agree with their obvious algebra, it is clearly not ap…
The complex relation between production and scattering amplitudes
Eef van Beveren, George Rupp
The unitarity relation, Im(A)=T* A, is derived for a three-body production amplitude, A, that consists of a complex linear combination of elements of the two-body scattering amplit…
How we discovered the nonet of light scalar mesons
Eef van Beveren, George Rupp
As has been confirmed meanwhile by lattice-QCD calculations (see e.g. hep-lat/0702023), the confinement spectrum of non-exotic quark-antiquark systems has its ground state for scal…
A low-lying scalar meson nonet in a unitarized meson model
E. van Beveren, T. A. Rijken, K. Metzger +3
A unitarized nonrelativistic meson model which is successful for the description of the heavy and light vector and pseudoscalar mesons yields, in its extension to the scalar mesons…
Constituent and current quark masses at low chiral energies
M. D. Scadron, F. Kleefeld, G. Rupp
Light constituent quark masses and the corresponding dynamical quark masses are determined by data, the Quark-Level Linear Model, and infrared QCD. This allows to define effect…
