摘要

MINERvA, a dedicated neutrino-nucleus scattering experiment, was designed to study neutrino cross sections with high precision. These measurements play a crucial role in probing nuclear structure, understanding nuclear medium and final-state interaction effects, and validating existing theoretical models. A key feature of MINERvA is its use of nuclear targets of different atomic masses (A) exposed to the same neutrino beam and placed in the same geometric apparatus, allowing for direct measurements of the nuclear dependence of cross sections. This approach significantly reduces flux- and detector-related uncertainties, leading to more precise results. Precise measurements of neutrino cross sections are essential, as uncertainties in these measurements propagate directly to the determination of key neutrino oscillation parameters, impacting the accuracy of oscillation studies. In this work, we present an overview of three of the latest results published by the MINERvA Collaboration, demonstrating the experiment’s significant contributions to the field. With 46 published papers to date, MINERvA continues to provide valuable insight that advance our understanding of neutrino interactions. Furthermore, the experiment currently has 30 ongoing analyses, with many more exciting results to be anticipated in the near future.
