Sumario:In this Thesis we present a wide analysis of nuclear effects which are crucial for a proper description of neutrino-nucleus scattering. We use a well-established many-body framework, successful in modelling a great variety of nuclear processes. In particular, we analyze the role of the spectral functions (SF) accounting for the modifications of the dispersion relation of nucleons embedded in the nuclear medium. We concentrate on processes mostly governed by one-body mechanisms, studying possible approximations to evaluate the particle-hole propagator using spectral functions and performing a series of analyses and comparisons with other approaches for the quasielastic mechanism.
