Neutrino Interactions: are all the standard ν-properties “free citizens” of Terra Cognita?

The discovery of the neutrino non-standard properties (mass and mixing) refocused on various aspects of the neutrino standard properties, both from the theoretical and the experimental side. This concerns in particular the ν interactions cross-sections in the intermediate energy range (∼ 0.5-5 GeV). In this review we offer a qualitative summary of the achievements from the current activity in this field.
