Title: Charm Production in Neutrino-Nucleon Deep Inelastic Scattering at NuTeV

Abstract: 

We present measurements of the semi-inclusive cross-sections for 
nu_mu-nucleon deep inelastic scattering interactions with two oppositely
charged muons in the final state. These events dominantly arise from
production of a charm quark during the scattering process. The 
measurement was obtained from the analysis of 5102 nu_mu induced
and 1458 nu_mu charge conjugate induced events collected with the NuTeV
detector exposed to a sign selected beam at the Fermilab Tevatron. We also
extract cross-section measurement from a re-analysis of 5030 nu_mu
induced and 1060 nu_mu= induced events collected from the exposure of the
same detector to a quad-triplet beam by the CCFR  experiment.
The results are combined to obtain the most statistically precise
measurement of neutrino-induced dimuon production cross-sections to date.
These measurements should be of broad use to phenomenologists interested
in the dynamics of charm production, the strangeness content of the
nucleon, and the CKM matrix element V_cd.
