Abstract

We have found 122 charmed-particle decays among 3855 neutrino interactions located in the fiducial volume of a hybrid emulsion spectrometer installed in the Fermilab wide-band neutrino beam. We obtain an average relative charmed-particle production cross section of σ(νμ→cμ-) σ(νμ→μ-)=4.9-0.6 +0.7%, at an average neutrino energy of 22 GeV. We also obtain a production rate of σ(νμ→ccνμ) σ(νμ→νμ)=0.13-0.11 +0.31%, if we assume that there was an undetected muon, a limit of σ(νμ→ccμ-) σ(νμ→cμ-)<3% (90%CL) can be obtained. Other cross section ratios and limits are also presented.
