D. Diakonov et al., EXOTIC ANTI-DECUPLET OF BARYONS - PREDICTION FROM CHIRAL SOLITONS, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 359(3), 1997, pp. 305-314
We predict an exotic Z(+) baryon (having spin 1/2, isospin 0 and stran
geness +1) with a relatively low mass of about 1530 MeV and total widt
h of less than 15 MeV. It seems that this region of masses has avoided
thorough searches in the past.
