Description
Next-generation long-baseline neutrino experiments aim to measure neutrino oscillation parameters with percent-level precision and to determine the CP-violating phase in the lepton sector of the Standard Model. Achieving these ambitious goals requires a significantly improved understanding of neutrino–nucleus interaction cross sections, which currently constitute one of the dominant sources of systematic uncertainty. Electron-scattering experiments can provide essential constraints on nuclear response functions through high-statistics and high-precision measurements, since electrons probe the same vector current component involved in neutrino interactions. Such measurements therefore offer a powerful and complementary approach to reducing nuclear-model uncertainties.
In this contribution, recent results from electron-nucleus scattering experiments performed at MAMI will be presented, together with prospects for future studies at the upcoming MESA energy-recovery accelerator facility.
