Abstract |
|
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 $\kappa=0.33+-0.05+-0.05$, improving the results obtained in similar analyses by previous experiments. |
