Modeling Neutrino and Electron Scattering Cross Sections in the Few GeV Region with Effective $LO PDFs$

Abstract

We use new scaling variables $x_w$ and $\xi_w$, and add low $Q^2$ modifications to GRV94 and GRV98 leading order parton distribution functions such that they can be used to model electron, muon and neutrino inelastic scattering cross sections (and also photoproduction) at both very low and high energie.Comment: 8 pages, 3 figures, Invited talk given by Arie Bodek at the X Mexican School of Particles and Fields, Playa del Carmen, Mexico, 200
