Description
We report on an update (2021) of a phenomelogical model for inelastic neutrino- and electron- nucleon scattering cross sections using effective leading order parton distribution functions with a new scaling variable ξw. Non-perturbative effects are well described using the ξw scaling variable in combination with multiplicative K factors at low Q2. The model describes all inelastic charged lepton-nucleon scattering data (HERA/NMC/BCDMS/SLAC/JLab) ranging from very high Q2 to very low Q2 and down to the Q2 = 0 photo-production region. The model has been developed to be used in analysis of neutrino oscillation experiments in the few GeV region. The 2021 update accounts for the difference between axial and vector structure function which brings it into better agreement with existing inelastic neutrino-nucleon scattering measurements.
