Electron-nucleus scattering at MAMI as a benchmark for precision neutrino interaction models. — •Khwaja Idrees Hassan and Luca Doria — Institut für Kernphysik, JGU Mainz

Achieving the precision required for next-generation neutrino experiments depends critically on a detailed understanding of the fundamental processes governing neutrino-nucleus interactions in detectors. At present, uncertainties associated with these interactions remain at the O(10%) level, whereas upcoming experiments demand O(1%) precision.

Electron-nucleus scattering provides a high-precision benchmark for event generator codes used in neutrino experiments, helping reduce systematic uncertainties and ensure the consistency of nuclear models.

The A1 Collaboration at MAMI has initiated an experimental program to precisely measure nuclear cross sections relevant to neutrino physics, with particular emphasis on the needs of future long-baseline experiments such as DUNE and Hyper-Kamiokande. In this contribution, we present current results on ¹²C and ⁴⁰Ar cross-section measurements and provide an outlook on future experiments for ¹⁶O.
