The main objective of the PhD thesis is to develop the general formalism needed to describe semi-inclusive neutrino-nucleus scattering reactions, and apply this study to the analysis of recent experiments performed at several international collaborations: MiniBooNE, DUNE, T2K, Minerva, etc. The overall aim of these studies is to improve the understanding of the neutrino oscillation phenomenon. A proper neutrino oscillation analysis requires to have an excellent control on the nuclear uncertainties involved. At present most of the investigations related to neutrino-nucleus scattering concern inclusive measurements where only the scattered lepton is detected, but the proper description of the hadrons and mesons in the final-state will be essential for the next-generation of neutrino experiments. This is connected to the fact that modern experimental studies of neutrino-nucleus reactions rely on the use of data simulations to determine the behavior of the detectors involved. This requires having a reasonable control on the reconstruction of the energy neutrino which can be only achieved by analyzing the kinematics of the final particles. This clearly shows the importance to have realistic theoretical predictions corresponding to more exclusive processes where, in addition to the final lepton, other particles are detected. The extension of nuclear models to semi-inclusive reactions is one of the main challenges to be faced by nuclear theorists working in this field. Some of the basic objectives pursued in this PhD project are the following: *Check the fully relativistic calculations by recovering the inclusive cross sections from the semi-inclusive ones by integrating over the final nucleon (undetected) variables (Done and published on 2020). *Evaluate and analyze in detail the semi-inclusive cross section corresponding to the relativistic plane wave impulse approximation (RPWIA), but with different nuclear models:relativistic Fermi Gas (RFG), relativistic mean field (RMF) and spectral function (SF) models (Done and published on 2021). *Implement final-state interactions in semi-inclusive neutrino reactions within a fully relativistic framework and compare with all available experimental data (Work in progress). *Finally, study the incorporation in the fully relativistic formalism the contribution of effects beyond the impulse approximation, namely, the role played by Meson Exchange Currents (MEC) (planned for late 2022-2023).
