Measurement of the ¹²C(e,e') cross sections at Q²=0.8\,GeV²/c²

We present the findings of a study based on a new inelastic electron-scattering experiment on the ¹²C nucleus focusing on the kinematic region of Q²=0.8\,GeV²/c². The measured cross section is sensitive to the transverse response function and provides a stringent test of theoretical models, as well as of the theoretical assumptions made in Monte-Carlo event-generator codes developed for the interpretation of neutrino-nucleus experiments, such as DUNE and HyperK. We find that modern generators such as GENIE and GiBUU reproduce our new experimental data within 10$%$.
