摘要

We report on the observation of a narrow resonance in D^{*-}p and D^{*+} pbar invariant mass combinations in deep-inelastic ep scattering at centre-of-mass energies of 300 and 320 GeV at HERA. The mass of the resonance is measured to be 3099 +- 3 (stat.) +- 5 (syst.) MeV, the Gaussian width of 12 +- 3 (stat.) MeV is compatible with the experimental resolution. The state can be interpreted as an anti-charmed baryon with minimal constituent quark composition $uudd\bar c$ , together with the charge conjugate.
