Abstract
We present the first next-to-leading-order QCD analysis of neutrino charm production, using a sample of 6090 - and -induced opposite-sign dimuon events observed in the CCFR detector at the Fermilab Tevatron. We find that the nucleon strange quark content is suppressed with respect to the non-strange sea quarks by a factor , where the error includes statistical, systematic and QCD scale uncertainties. In contrast to previous leading order analyses, we find that the strange sea -dependence is similar to that of the non-strange sea, and that the measured charm quark mass, , is larger and consistent with that determined in other processes. Further analysis finds that the difference in -distributions between and is small. A measurement of the Cabibbo-Kobayashi-Maskawa matrix element is also presented. uufile containing compressed postscript files of five Figures is appended at the end of the LaTeX source.
