The x-dependence of Parton Distributions Compared with Neutrino Data
Abstract
We use the variational principle of Quantum HadronDynamics, an alternative formulation of Quantum ChromoDynamics, to determine the wavefunction of valence quarks in a baryon at a low value of Q2. This can be used to predict the structure function xF3(x,Q2) at higher values of Q2 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.
