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. In particular, precise measurements and modeling of the v-Nucleus Cross-Section in the intermediate energy range (similar to 0.5-5 GeV), and related Nuclear Effects, are now considered as fundamental issues.
... [Show full abstract] In fact, these become necessary for a more robust control of the systematic uncertainties relevant in the forthcoming experimental effort aiming at precision measurements of the MNSP matrix elements. A critical review of the present knowledge motivated the origin and the activity of a wide community progressively formed around these issues. In this introductory review we provide with a qualitative summary of the achievements from the current activity in this field.
