Popis: In this paper we present the results of a search for the charmed strange baryon Ξc+ in the final states Λ0π+π+K− and Ξ−π+π+. The experiment was performed using the magnetic spectrometer BIS-2 with a hydrogen target located in the neutron beam of the Serpukhov accelerator. A narrow peak in the Λ0π+π+K− state is observed at a mass of ≈2440 and possibly also of ≈2310 MeV/c2, corresponding to signals for the Ξc+ → Λ0π+π+K− and Ξc+ → Σ0π+π+K− (Σ0 → Λ0γ) decays respectively. The statistics obtained for the Ξ−π+π+ state is too low to make any conclusion.
