NuSTEC White Paper: Status and Challenges of Neutrino-Nucleus Scattering

Understand

The precise measurement of neutrino properties is among the highest priorities in fundamental particle physics, involving many experiments worldwide.

• Since the experiments rely on the interactions of neutrinos with bound nucleons inside atomic nuclei, the planned advances in the scope and precision of these experiments requires a commensurate effort in the understanding and modeling of the hadronic and nuclear physics of these interactions, which is incorporated as a nuclear model in neutrino event generators.
• This model is essential to every phase of experimental analyses and its theoretical uncertainties play an important role in interpreting every result.
• In this White Paper we discuss in detail the impact of neutrino-nucleus interactions, especially the nuclear effects, on the measurement of neutrino properties using the determination of oscillation parameters as a central example.
