Title: Observation of decays of charmed D mesons and a summation/sup ++//sub c/ (2450) baryon produced in neutrino interactions with nuclei in nuclear emulsion

Abstract

Results are reported of a search for and analysis of decays of charmed particles produced in interactions of neutrinos with nuclei in nuclear emulsion. Cryogenically sensitive nuclear emulsion was placed in the 15-foot bubble chamber at the Fermi National Accelerator Laboratory and bombarded in a neutrino beam with a broad energy spectrum up to 200 GeV. The search for interactions was carried out along the track in horizontally bombarded layers of emulsion with use of a target indication system. Decays of a ..lambda../sup +//sub c/ baryon, a D/sup +/ meson, and two D/sup 0/ mesons were recorded. The event with decay of a ..lambda../sup +//sub c/ baryon is interpreted as the production and decay of the charmed baryon resonance summation/sup ++//sub c/ (2450) into ..lambda../sup +//sub c/..pi../sup +/.
