11 Decay modes

12 S=-1,I=0 Channel

13 S=-1,I=0 Channel

14 S=-1,I=1Channel

16 [hep-ph]

17 Radiative decay into γandΒD

18 Decay width for radiative decay

19 ρωφCouplings of resonances

20 Decay widths [hep-ph]

21 Conclusions Ten resonances in the different strangeness and isospin channels. Degenerate in JP=1/2-, 3/2-, 5/2-. Radiative widths are of the order of 1MeV. Radiative decay widths are different about one order of magnitude between the widths for different charge states of the same resonance.
