Research and Development for Near Detector Systems Towards Long Term Evolution of Ultra-precise Long-baseline Neutrino Experiments

With the discovery of non-zero value of $\theta_{13}$ mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically significant samples of muon and electron neutrinos and anti-neutrinos with large oscillation effects. In this document we intend to highlight the importance of Near Detector facilities in LBN experiments to both constrain the systematic uncertainties affecting oscillation analyses but also to perform, thanks to their close location, measurements of broad benefit for LBN physics goals. A strong European contribution to these efforts is possible

Neutrino interaction with matter

Neutrino interactions with atomic nuclei, generating the signals used to detect neutrino oscillations, are a unique example of how, in a scattering process, the roles of probe, target, and detector can become interchangeabl

Interazione dei neutrini con la materia

Le interazioni tra i neutrini e i nuclei atomici, che generano i segnali utilizzati per rivelare le oscillazioni dei neutrini, sono un esempio unico di come, in un processo di diffusione, i ruoli di sonda, bersaglio e rivelatorepossano diventare intercambiabil
