Remarks on meson loop effects on quark models
I. K. Hammer, C. Hanhart, A. V. Nefediev
We investigate the effect of meson loops on the spectrum of quark states. We demonstrate that in general quark states do not tend to get very broad if their coupling to the continu…

Heavy-quark spin symmetry partners of the revisited
V. Baru, E. Epelbaum, A. A. Filin +3
We revisit the consequences of the heavy-quark spin symmetry for the possible spin partners of the . We confirm that, if the were a molecular state…

Interplay of quark and meson degrees of freedom in near-threshold states: A practical parametrisation for line shapes
F. -K. Guo, C. Hanhart, Yu. S. Kalashnikova +5
We propose a practical parametrisation for the line shapes of near-threshold states compatible with all requirements of unitarity and analyticity. The coupled-channel system underl…
