The neutrino-nucleus reactions are studied at energies from 0 to 3 GeV, using the CRISP program. To simulate these reactions, CRISP uses the Monte Carlo method through an intranuclear cascade model. Quasielastic, baryonic resonance formation, and deep inelastic scattering channels for the neutrino-nucleon interaction are considered. The total and differential particle emission cross sections were obtained, resulting in a good agreement with the values reported by the MiniBooNE experiment. The influence of nuclear effects on the studied reactions, such as fermionic motion and the Pauli blocking mechanism, was shown. By using only neutrino-nucleon interactions (1p1h), it was necessary to modify the axial mass of the quasielastic channels to MA=1.35 GeV (much higher than the value obtained in neutrino-deuterium reactions, MA=1.026 GeV ). The problem in adjusting MA is the need for known MA(A ), where A is the mass number, in case we want to study another target nucleus. The introduction of the 2p2h processes solves this and also reproduces the experimental data with MA=1.026 GeV . To show this, we use the transverse enhancement model to implement the 2p2h dynamic in CRISP, in such a way that it can be used with any target nucleus.
