Measurement of charm production in antineutrino charged-current interactions
During the years 1994-97, the emulsion target of the CHORUS detector was exposed to the wideband neutrino beam of the CERN SPS collecting about 10^6 neutrino interactions. A measurement of nubar_mu-induced charm production is performed by usingthe presence of a 5% nubarmu component in the nu_mu beam...

| description | During the years 1994-97, the emulsion target of the CHORUS detector was exposed to the wideband neutrino beam of the CERN SPS collecting about 10^6 neutrino interactions. A measurement of nubar_mu-induced charm production is performed by usingthe presence of a 5% nubarmu component in the nu_mu beam. The measurement takes advantage of the capability to observe the decay topology in the emulsion. The analysis is based on a sample of charged-current interactions with at least one identified muon. About 100 000 vere located in the emulsion target and fully reconstructed. By requiring a positive muon charge as determined by the CHORUS spectrometer, 32-nubar_mu induced charm events were observed with an estimated background of 3.2 events. At an average antineutrino energy in the neutrino beam of 18GeV, the charm production rate induced by anitneutrinos is measured to be sigma(nubar_muN -> mu+cbarX)/sigma(nubar_muN -> mu+X) = (5.0^+1.4_-0.9(stat) +- 0.7(syst))%. The ratio between neutral and charged charm production rates in this process is (2.6^+1.7_-1.0(stat) +- 0.8(syst)). The charm production rate as a function of the antineutrino energy is found to be in good agreement with previous results derived from di-lepton data. |
