Monte Carlo event generation of neutrino–electron scattering

We describe an extension of the NuWro Monte Carlo neutrino event generator with neutrino-electron scattering processes. This new dynamical channel includes charged current and neutral interactions, together their interference, for $\nu_\ell e$ $\bar\nu_\ell ($\ell=e,\mu,\tau$) scatterings, resulting in ten possible final states. illustrate performance functionality on few physical examples, including estimation background T2K $\nu_\mu\rightarrow\nu_e$ oscillation experiment. show that events arising from interactions occupy mostly a distinct region phase space can be easily separated.
