Search for a narrow charmed baryonic state decaying to $D^{ast pm} p^mp$ in ep collisions at HERA Academic Article uri icon

abstract

  • A resonance search has been made in the D*p invariant-mass spectrum with the ZEUS detector at HERA using an integrated luminosity of 126 pb-1. The decay channels D*+ - D0s+ (K -+)s+ and D*+ D0s+ (K-++-) s+ (and the corresponding antiparticle decays) were used to identify D* mesons. No resonance structure was observed in the D* p mass spectrum from more than 60 000 reconstructed D* mesons. The results are not compatible with a report of the H1 Collaboration of a charmed pentaquark, c0. Springer-Verlag / Societ Italiana di Fisica 2004.
