In neutrino oscillation experiments, neutrino interactions at the detector are simulated using event generators which attempt to reflect our understanding of nuclear physics. We study the impact of different neutrino interactions and nuclear models on the determination of neutrino oscillation parameters. We use two independent neutrino event generators, Generates Events for Neutrino Interaction Experiments (GENIE) 2.8.0 and Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) 2.6, and apply them to a setup with a conventional neutrino beam aiming at a water Čerenkov detector, for which only the charged-current quasielastic–like sample is selected. Subsequently, we perform a fit to the oscillation parameters in the ${\nu }_{\mu }$ disappearance channel.
