Abstract

The three pentaquark candidates Theta(+)(1530), Xi(1862) and Theta(0)(c)(3100) have been studied in ep collisions at a centre-of-mass energy root 8 = 300 - 318 GeV using the fun luminosity of the HERA-I data. Searches for narrow baryonic states in the decay channels K(S)(0)p, K(+)p, Xi(-) pi(+/-), Xi(+) pi(+/-) and D*(+/-) p(-/+) are reported. The results support the existence of a narrow resonance decaying into K(S)(0)p and K-S(0)(p) over bar consistent with the Theta(1530) state. No signals are seen in the K(+)p, Xi(-) pi(+/-), Xi(+) pi(+/-) and D*(+/-) p(-/+) channels.
