Neutrino-induced pion production at energies relevant for the MiniBooNE and K2K experiments

Abstract

We investigate charged and neutral current neutrino induced incoherent pion production off nuclei at MiniBooNE and K2K energies within the GiBUU model. We assume impulse approximation and treat the nucleus as a local Fermi gas of nucleons bound in a mean-field potential. In-medium spectral functions are also taken into account. The outcome of the initial neutrino nucleon reaction undergoes complex hadronic final state interactions. We present results for neutral current ${\ensuremath{\pi}}^{0}$ and charged current ${\ensuremath{\pi}}^{+}$ production and compare to MiniBooNE and K2K data.
