Abstract
We report on a measurement of the neutrino-nucleon and antineutrino-nucleon differential cross sections in the CCFR detector. The measurement of the d ifferential cross sections over a wide range of energies allows Delta xF(3) = xF(3)(v)-xF(3)((v) over bar) and R to be extracted. Delta xF(3) is relat ed to the difference between the contributions of the strange and charm sea s in the nucleon to production of massive charm quark. The results for Delt a xF(3) are compared to various massive charm NLO QCD models. The Q(2) depe ndence of R for x < 0.1 has been measured for the first time.
