In order to achieve the precise measurement of the neutrino oscillation, an accurate understanding of the neutrino beam and the neutrino interaction is essential.
Such measurements include a value for m a from the observed q 2 distribution of the events, the neutrino qe interaction cross section, and differential cross sections. A comparison between modern measurements of these quantities and the theory discussed in section 3 immediately reveals several discrepancies.

Because neutrinos only weakly interact with other particles of matter, neutrino to earth decreases with increasing energy, the size of neutrino detectors must.
Measurements of final-state neutron multiplicity from neutrino-nucleus interactions will improve our understanding of the complex, many-body dynamics of neutrino-nucleus interactions and thus help to reduce dominant systematics on future long-baseline neutrino oscillation measurements.
At current stage, understanding neutrino interactions with matter plays an important role in reducing impact of systematic effects on the neutrino oscillation measurement, especially when we are stepping into the precision era and exploring cp violation, mass hierarchy.

Neutrino interactions and inelasticity there’re 3 cases of detections: - at tev scale, neutrino-nucleon interactions are expected to be dominated by deep inelastic scattering (dis) - must consider the neutral current (nc) and charged current (cc) contributions - scattering with sea s quarks is also possible.
Scintillator-based neutrino detectors will continue to be important for the next set of neutrino measurements, from the determination of the neutrino mass hierarchy [7,8] to elastic scattering measurements [9] and sterile neutrino searches [10,11], and for non-proliferation applications [12,13].
Neutrino oscillations have been probed during the last few decades using multiple neutrino sources and experimental set-ups.

One of the defining properties of neutrinos is their extremely feeble interaction with neutrinos. While increasingly powerful accelerators with proton beams approaching 1 megawatt of power are being used to produce neutrinos, enormous detectors with tons (for near/short base line detectors ~100 m away from the source) or kilotons (for far detectors ~1000 km from the source) of mass are needed.
