Description

The results are presented on the experimental search and analysis of decays of charmed particles produced in neutrino-emulsion interactions. In the present experiment cryogenically sensitive BR2 emulsions were placed into Fermilab 15-foot bubble chamber and were exposed in the broad energy spectrum (10-200 GeV) neutrino beam. The method of the search for the interactions by using a track following technique in a horizontally exposed pellicles in hybrid experiments is considered. The decays of Λc+-baryon, D+ and two D0-mesons are found. The event with Λc+-decay is interpreted as a production and decy of a charmed baryon resonance Σc++(2450) on Λc+π+
