This can be used to predict the structure function xF_3(x,Q^2) at higher values of Q^2 using the evolution equations of perturbative QCD. This prediction is compared to the measurements of neutrino scattering cross-section by the CDHS and CCFR experiments. The agreement is quite good, confirming the validity of QHD as a way of studying hadronic structure.5 pages, RevTexHigh Energy Physics - PhenomenologyThe x-dependence of Parton Distributions Compared with Neutrino Datatext
