Search for CHARM pentaquarks in ZEUS at HERA

(ZEUS Collaboration) Using the full 1996 - 2000 ZEUS data at HERA (121 pb-1) we have searched for the c0{expression}(3100) pentaquark in the photoproduction and DIS regime. The search has yielded negative results. The 95% C.L. upper limits on the visible rate R(c0{expression} - > D*p/D*) is 0.23%...

Zusammenfassung:(ZEUS Collaboration) Using the full 1996 - 2000 ZEUS data at HERA (121 pb-1) we have searched for the c0{expression}(3100) pentaquark in the photoproduction and DIS regime. The search has yielded negative results. The 95% C.L. upper limits on the visible rate R(c0{expression} - > D*p/D*) is 0.23% (0.35% for DIS).
