Observation of a hadronic interference effect in annihilation processes
Eef van Beveren, George Rupp
We present evidence for small oscillations we observe in electron-positron and proton-antiproton annihilation data, with a periodicity of 76+-2 MeV, independent of the beam energy.…
The quark-antiquark spectrum from upside down
Eef van Beveren, George Rupp
We argue that the spectra of quark-antiquark systems should better be studied from higher radial excitations and, in particular, from configurations with well-defined quantum numbe…
Light and heavy at the end of the funnel
Eef van Beveren, George Rupp
We show that, by taking a bare mass spectrum with constant spacings for the quark-antiquark propagators, which is subject to considerable mass shifts from meson loops, one adequate…
Delicate interplay between the D0-D*0, rho0-J/psi, and omega-J/psi channels in the X(3872) resonance
Susana Coito, George Rupp, Eef van Beveren
The nature of the X(3872) enhancement is analysed in the framework of the Resonance-Spectrum Expansion, by studying it as a regular charmonium state, though strongl…
Evidence for the psi(5S) and psi(4D) c-cbar vector resonances
Eef van Beveren, George Rupp
We present evidence for the psi(5S) and psi(4D) c-cbar vector resonances in experimental data published by the Belle and BaBar Collaborations. Central masses and resonance widths a…
Complex masses in the S-matrix
George Rupp, Susana Coito, Eef van Beveren
Most excited hadrons have multiparticle strong decay modes, which can often be described as resulting from intermediate states containing one or two resonances. In a theoretical ap…
Coupled-channel analysis of the X(3872)
S. Coito, G. Rupp, E. van Beveren
The X(3872) is studied as an axial-vector charmonium state in the multichannel framework of the Resonance-Spectrum-Expansion quark-meson model, previously applied to a variety of o…
A very broad X(4260) and the resonance parameters of the 3D vector charmonium state
Eef van Beveren, George Rupp, J. Segovia
We argue that the X(4260) enhancement contains a wealth of information on vector c-cbar spectroscopy. We discuss the shape of the X(4260) observed in the OZI-forbidden process "ele…
Evidence for further charmonium vector resonances
Eef van Beveren, George Rupp
We discuss the shape of threshold signals in production cross sections of the reaction e+ + e- --> D* + antiD*, at the opening of the D(s)* antiD(s)* and Lambda(c)+ Lambda(c)- chan…
