Neutrino production of charmed particles in a hybrid experiment E-564

Cryogenically sensitive nuclear emulsion was placed inside the 15-foot bubble chamber of FNAL and exposed to a wide-band energy (up to 200 GeV) neutrino beam. 194 charged-current neutrino interactions and 13 decays of charmed particles were registered. Using the nuclear emulsion as a vertex detector with the good spectrometric properties of the 15-foot bubble chamber has allowed the decays of charmed particles to be effectively analysed. Attentions is focussed on the new physical results. Λ c + baryon andD s + meson decay channels, production of charmed ∑ c baryons and Λ c + via ∑ c . For the first time an event interpreted as production of the excited (c\(\overline s\))-state with mass ∼2790 MeV/c2 has been registered.
