Simulations from a new neutrino event generator

Abstract

We construct a new Monte Carlo generator of events for neutrino interactions. The dynamical models for quasi-elastic reactions, $Δ$ excitation and more inelastic events described by the DIS formalism with the PDFs modified according to recent JLab data are used. We describe in detail single pion production channels, which combine the $Δ$ excitation and DIS contribution. Many comparisons of the outcome of simulations with experimental data are presented.
