Query: High-energy neutrino-nucleus interactions   High-energy neutrino-nucleus interactions are discussed by considering
neutrino-oscillation experiments and ultra-high-energy cosmic neutrino
interactions. The largest systematic error for the current neutrino oscillation
measurements comes from the neutrino-nucleus interaction part, and its accurate
understanding is essential for high-precision neutrino physics, namely for
studying CP violation in the lepton sector. Depending on neutrino beam
energies, quasi-elastic, resonance, Regge, or/and deep inelastic scattering
(DIS) processes contribute to the neutrino cross section. It is desirable to
have a code to calculate the neutrino-nucleus cross section in any kinematical
range by combining various theoretical descriptions. On the other hand, the
IceCube collaboration started obtaining cross section data up to the $10^{15}$
eV range, so that it became necessary to understand ultra-high-energy neutrino
interactions beyond the artificial lepton-accelerator energy range. For future
precise neutrino physics including the CP measurement, it is also necessary to
understand accurate nuclear corrections. The current status is explained for
nuclear corrections in DIS structure functions. The possibility is also
discussed to find gravitational sources within nucleons and nuclei, namely
matrix elements of quark-gluon energy-momentum tensor. They could be probed by
neutrino interactions without replying on direct ultra-weak "gravitational
interactions" with high-intensity neutrino beams, possibly at a future neutrino
factory, by using techniques of hadron tomography.
