The non-ordinary Regge behavior of the K 0 ∗ ( 800 ) or κ -meson versus the ordinary K 0 ∗ ( 1430 )

The Regge trajectory of an elastic resonance can be calculated from dispersion theory, instead of fitted phenomenologically, using only its pole parameters as input. This also provides a correct treatment of resonance widths in Regge trajectories, essential for very wide resonances. In this work we...
