Recent progress in neutrino scattering experiments with few GeV neutrino beams is reviewed, focusing on new experimental input since the beginning of the NuInt workshop series in 2001. Progress in neutrino quasi-elastic scattering, resonance production, coherent pion production, scattering in the transition region between the resonance and deep inelastic regimes, and nuclear effects in neutrino...

The virtuality of the target photon, P , has to be much smaller than the virtuality Q of the probe photon such that the neglected terms of order O(P /Q) are small. In the following, we are interested in the photon structure function F γ(P ) 2 (x,Q ) which enters the deep inelastic electron photon cross section in exactly the same way as is well known from deep inelastic electron proton scattering
