The experimental search for CHARM pentaquarks in the ZEUS detector at HERA

Using the full 1996 - 2000 ZEUS data at HERA (121 pb-1) we have searched for the Theta0c(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(ThetaDGc -+D*p/D*) is 0.23% (0.35% for DIS).
