✦ Synopsis


We report on a measurement of the neutrino-nucleon and antineutrino-nucleon differential cross sections in the CCFR detector. The measurement of the differential cross sections over a wide range of energies allows AxF3 = xF~-xF'~ and R to be extracted. AxF3 is related to the difference between the contributions of the strange and charm seas in the nucleon to production of massive charm quark. The results for AxF3 are compared to various massive charm NLO QCD models. The Q2 dependence of R for x < 0.1 has been measured for the first time.
