Q 2 dependence of the proton and neutron structure functions from neutrino and antineutrino scattering in deuterium

12,100 νD and 10,500\(\bar vD\) charged current interactions in deuterium measured in the BEBC bubble chamber were used to obtain the complete set of structure functions of proton and neutron. Thex andQ2 dependence of the structure functions of up and down valence quarks and antiquarks are presented and discussed. The Adler and Gross-Llewellyn Smith sum rules have been tested at differentQ2 values. A QCD analysis of the four non singlet structure functionsxF 3 νN ,xu v ,xd v andF 2 νn −F 2 νp has been performed yielding values ofΛLO between 100 and 300 MeV.
