Exotic anti-decuplet of baryons: prediction from chiral solitons

  • Dmitri Diakonov

We predict an exotic Z + baryon (having spin 1/2, isospin 0 and strangeness +1) with a relatively low mass of about 1530 MeV and total width of less than 15 MeV. It seems that this regionof masses has avoided thorough searches in the past.
