Neutrinos are among the most intriguing particles in the universe, offering a unique window into fundamental questions in particle physics and cosmology. These elusive, “ghost-like” particles challenge the Standard Model and hold the potential to reveal new physics. Worldwide collaborations are actively studying neutrinos, with long-baseline experiments leading the charge.

Future experiments, such as the Deep Underground Neutrino Experiment (DUNE), aim to make groundbreaking measurements of neutrino oscillation parameters, Charge-Parity (CP) violation in the lepton sector, and the neutrino mass hierarchy. Achieving these goals requires highly precise interaction models, which remain a significant challenge to develop.

In this talk, we will explore the difficulties in constructing these models and how experiments like MINERvA provide crucial data to refine them, paving the way for the next generation of neutrino discoveries.
