Electron-Nucleus Cross-Section Measurements at MAMI for Neutrino Physics — •Luca Wilhelm, Maximilian Littich, and Luca Doria — Institute for Nuclear Physics, Johannes Gutenberg-University Mainz, Germany

Electron scattering experiments are powerful tools for studying problems in nuclear physics. Recently, theoretical ab-initio methods extended their reach to medium-mass nuclei opening up new opportunities for precise electron scattering experiments. Such experiments can elucidate the role of different effects in the nuclear dynamics, ranging from excited states to collective phenomena and nucleon resonances in the nuclear medium. Furthermore, neutrino physics needs precise nuclear physics input for reaching the ambitious goals set by next-generation long-baseline experiments. Due to the similarity between electrons and neutrinos, theoretical models and neutrino generators can be tested and improved through the comparison to precise electron scattering experiments. At the MAMI accelerator, we performed and inclusive cross-section measurements on different nuclei relevant for neutrino physics: ¹²C, ¹⁶O, ⁴⁰Ar. The collected data will be used to test the predictions of different theoretical calculations and generators.
