Abstract
S = +1 baryon interpolating operators were proposed, which are based on a exotic description of the antidecuplet bayron, like the diquark-diquark- antiquark structure. The mass spectrum of the spin-1/2 pentaquark states was calculated by using the operator. It was observed that the Jp assignment of the θ state was most like (1/2)-. The mass of the charm analog of the θ was also calculated and the θ state lies much higher than the DN threshold.
