Investigation of the Lightest Hybrid Meson Candidate with a Coupled-Channel Analysis of -, - and -Data
B. Kopf, M. Albrecht, H. Koch +4
A sophisticated coupled-channel analysis is presented that combines different processes: the channels , and from annihilations, the P- and D…
Charmed Exotics
G. Bali, A. Denig, S. I. Eidelman +5
These are the mini-proceedings of the CHARMEX workshop. The meeting focused on recent developments in charm spectroscopy, especially on the possible role of the states that do not…
Methods and Models for Hadron Physics
C. Davies, S. Faccini, H. Lipkin +18
A round table held during the Hadron07 Conference focusing on experimental observations of new hadronic states, on theoretical perspectives for their description, and on the role o…
molecule as an axial meson
Su Houng Lee, Marina Nielsen, Ulrich Wiedner
We use QCD sum rules to study the possible existence of a molecule with the quantum number . We consider the contributions of condensates up t…
Glueballs, closed fluxtubes and eta(1440)
Ludvig Faddeev, Antti J. Niemi, Ulrich Wiedner
The component of the pseudoscalar has strong affinity for glue. But its mass is incompatible with lattice simulations that predict a much higher value for t…
