Search for a narrow charmed baryonic state decaying to 
in ep collisions at HERA
A resonance search has been made in the invariant-mass spectrum with the ZEUS detector at HERA using an integrated luminosity of 
. The decay channels 
and 
(and the corresponding antiparticle decays) were used to identify 
mesons. No resonance structure was observed in the mass spectrum from more than 60 000 reconstructed mesons. The results are not compatible with a report of the H1 Collaboration of a charmed pentaquark, 
.
