Consider the neutrino cross-section on an electron

o(v,e Vue)

and on an ‘average nucleon’ (namely the average between the cross-sections on protons and neutrons)

→µh) z 0.2 ×

at energies √s >> m, where m is the target mass and h is any hadronic state (the factor 0.2 is due to the quark distribution inside the nucleus). Calculate their ratio at E_v = 50 GeV. How does this ratio depend on energy? Calculate σ/E_v for the two reactions.
