1)Leptonic weak interactions:
Could you explain  meaning of "charged currecnt lepton universality"?
Draw illustrative Fenman diagrams and write down formulas.
Whta is the experimental evidince for it?

2) Neutrino-quark and anti-neutrino-quark scattering.
What is characteristic about it, that differs from lepton-quark scattering.
Write down formulas for cross-sections and explain origin of differences.

3) CDHS experiment at CERN studied deep inelastic neutrino scattering.
Explain the mesurement and main experimental results.
