Multichannel Description of Light and Intermediate Scalar Mesons
Susana Coito, George Rupp, Eef van Beveren
The light scalar mesons in a variety of approaches are briefly reviewed, as well as their description in the Resonance-Spectrum Expansion and related coupled-channel formalisms. A…
Comment on "Two-photon decay of the sigma meson"
Eef van Beveren, Frieder Kleefeld, George Rupp +1
We comment on a recent paper by Giacosa, Gutsche, and Lyobovitskij, in which it is argued that a quarkonium interpretation of the meson should give rise to a much smaller two-p…
The spectrum of charmonium in the Resonance-Spectrum Expansion
Eef van Beveren, George Rupp
We argue that the resonance-like structures Y(4260) (arXiv:hep-ex/0506081,arXiv:0707.2541), Y(4360), Y(4660) (arXiv:0707.3699) and Y(4635) (arXiv:0807.4458), which were recently re…
Possible psi(5S), psi(4D), psi(6S) and psi(5D) signals in Lambda(c)-antiLambda(c)
Eef van Beveren, Xiang Liu, Rita Coimbra +1
It is shown that the Lambda(c+)-Lambda(c-) signal recently reported by the Belle Collaboration (ARXIV:0807.4458) contains clear signs of the psi(5S) and the psi(4D) c-cbar vector s…
New c-cbar structure around 3764 MeV at BES and predictions from unquenching the confinement spectrum
Xiang Liu, Eef van Beveren, George Rupp
This paper has been withdrawn by the authors as a consequence of their misinterpretation of the BES experiment in 0807.0494
Radiative decays with a0(980) and f0(980) from ChPT at order p^4
S. Ivashyn, A. Korchin
A consistent description of the pi0 pi0 invariant mass distribution in the phi(1020) -> f0(980) gamma -> pi0 pi0 gamma decay and the pi0 eta in phi(1020) -> a0(980) gamma -> pi0 et…
