Exotic hadronic states at HERA
Abstract
Recent results from H1, ZEUS, HERMES and HERA-B on searches for exotic baryons in ep collisions, eD scattering and pA scattering at HERA are reviewed. Evidence for the production of the strange pentaquark Theta+ and of a narrow anti-charmed baryon decaying to D*-p together with negative results of pentaquark searches at HERA are presented.
