Measurement of the ${}^{12}\mathrm{C}(e,e^{\prime })$ cross sections at $Q^2=0.8{\mathrm{GeV}}^2/c^2$

Abstract

We present the findings of a study based on a new inelastic electron-scattering experiment on the ${}^{12}\mathrm{C}$ nucleus focusing on the kinematic region of $Q^2=0.8{\mathrm{GeV}}^2/c^2$. 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$\%$.
