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…

A practical parametrization for line shapes of near-threshold states
C. Hanhart, Yu. S. Kalashnikova, P. Matuschek +3
Numerous quarkonium(like) states lying near -wave thresholds are observed experimentally. We propose a self-consistent approach to these near-threshold states compatible with un…
