  16. Radiative decay into γandΒD

  17. Decay width for radiative decay

  18. ρωφCouplings of resonances

  19. Decay widths 0903.5138[hep-ph]

  20. 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.

  21. Thanks
