Unified approach for modelling neutrino and electron nucleon scattering cross sections from very high Q~2 to Q~2 = 0

摘要

We present the results of a new scaling variable, ξ_w in modelling neutrino- and electron-nucleon scattering cross sections using effective leading order PDFs. Our model desribes all deep inelastic scattering charged lepton-nucleon scattering data including resonance data (HERA/NMC/BCDMS/SLAC/JLab) from very high Q~2 to very low Q~2 (down to photo-productin region), as well as CCFR neutrino data. Non-perturbative QCD effects at low Q~2 region turn out to be well described by this new scaling variable. Our model is currently used for neutrino oscillation experiments at few GeV region.
