Following the establishment of neutrino oscillations using both astrophysical and terrestrial neutrino sources, we look forward to an exciting era when precision and high-sensitivity probes will refine our understanding of neutrino oscillations and elucidate their relationship to some of the "Big Questions" that confront the field of particle physics as a whole. Among these include the origins...

In neutrino scattering off nucleus, the uncertainties of the cross section come from the parameterization of the axial form factor and from nuclear effects. The approach currently applied in neutrino physics is to extract information about the elementary cross section (i.e. axial form factor) from scattering off nuclei. To make it possible, we have to describe nuclear effects in the most...

It is pointed out that so far all theoretical estimates of coherent pion production off nuclei induced by neutrinos rely on the 'local approximation' well known in photonuclear physics. The effects of dropping this approximation are discussed. It is found that in a plane wave approximation for the pion the local approximation overestimates the coherent neutrino-induced pion production on nuclei.
