Özet

We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the detector to the CERN Wide Band Neutrino Beam between 1995 and 1998. The analysis yields a value of the charm quark mass of m(c) = (1.26 +/- 0.16 +/- 0.09) GeV/c(2) and a value of the ratio of the strange to non-strange sea in the nucleon Of K = 0.33 +/- 0.05 +/- 0.05, improving the results obtained in similar analyses by previous experiments.
