There is an ongoing discussion on various aspects of the DPP 1997 prediction
of a relatively light and narrow exotic baryon.

1. Discussion of the validity of large N_c arguments for exotic baryons:

 Chiral soliton models, large Nc consistency... (T.Cohen)
 Exotic baryon multiplets at large number of colours (D. Diakonov and V. Petrov)
 Is Theta a kaon-skyrmion resonance? (N. Itzhaki et al.)
 Exotic baryons and the large-Nc expansion  (P. Pobylitsa)
 Exotic baryons as chiral solitons (pdf) (Diakonov's talk at the Institute for Advanced Studies, Princeton)
 The width of Theta for large Nc... (M. Praszalowicz)

2. Discussion of the phenomenological aspects:

 Chiral-soliton predictions for exotic baryons (J. Ellis, M. Karliner and M. Praszalowicz)
 Extraction of the pion-nucleon sigma term... (P. Schweitzer)
 Where are the missing members of the baryon antidecuplet? (D. Diakonov and V. Petrov)

3. Discussion of the arithmetical aspects:

The width of the Theta exotic baryon in the Chiral Soliton Model (R. Jaffe)
Comment on the Theta width and mass (D. Diakonov, V. Petrov and M. Polyakov)
