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…
Chiral Extrapolations of light resonances from dispersion relations and Chiral Perturbation Theory
Guillermo Ríos, Ángel Gómez Nicola, Christoph Hanhart +1
We review our recent study of the pion mass dependence of the rho and sigma resonances generated from one-loop SU(2) Chiral Perturbation Theory (ChPT) with the Inverse Amplitude Me…
Implications of heavy quark spin symmetry on heavy meson hadronic molecules
Feng-Kun Guo, Christoph Hanhart, Ulf-G. Meißner
In recent years, many heavy mesons and charmonia were observed which do not fit in the conventional quark model expectations. Some of them are proposed to be hadronic molecules. He…
Analytic properties of the scattering amplitude and resonances parameters in a meson exchange model
M. Döring, C. Hanhart, F. Huang +2
The analytic properties of scattering amplitudes provide important information. Besides the cuts, the poles and zeros on the different Riemann sheets determine the global behavior…
