“…It would be interesting to compare these results with earlier calculations of neutrino-induced pion production on nuclei by Paschos et al [11]. However, these authors have very recently found an error in their elementary pionproduction spectra [82] which affects their Figs.…”

Neutral current neutrino-nucleus interactions at intermediate energies

We have extended our model for charged current neutrino-nucleus interactions developed in Phys. Rev. C 73, 065502 (2006) to neutral current reactions. For the elementary neutrino-nucleon interaction, we take into account quasielastic scattering, ∆ excitation and the excitation of the resonances in the second resonance region. Our model for the neutrino-nucleus collisions includes in-medium effects such as Fermi motion, Pauli blocking, nuclear binding, and final-state interactions. They are implemented by means of the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) coupledchannel transport model. This allows us to study exclusive channels, namely pion production and nucleon knockout. We find that final-state interactions modify considerably the distributions through rescattering, charge-exchange, and absorption. Side-feeding induced by charge-exchange scattering is important in both cases. In the case of pions, there is a strong absorption associated with the in-medium pionless decay modes of the ∆, while nucleon knockout exhibits a considerable enhancement of low energy nucleons due to rescattering. At neutrino energies above 1 GeV, we also obtain that the contribution to nucleon knockout from ∆ excitation is comparable to that from quasielastic scattering.

“…Recently Lee and Sato [5] have developed a new model for weak production of the Ll resonance. Paschos and collaborators [6] have also contributed to this effort. It is noteworthy that the theoretical and exper imental picture of the resonance region is far more obscure than the quasi-elastic and deep-inelastic scattering (DIS) regions which border it and that much of the relevant MINOS event sample falls inside this poorly-understood resonance region.…”

The NuMI facility at Fermilab will provide an extremely intense beam of neutrinos for the MINOS neutrino-oscillation experiment. The spacious and fully-outfitted MINOS near detector hall will be the ideal venue for a high-statistics, high-resolution v and v-nucleon/nucleus scattering experiment.The experiment described here will measure neutrino cross-sections and probe nuclear effects es sential to present and future neutrino-oscillation experiments. Moreover, with the high NuMI beam intensity, the experiment will either initially address or significantly improve our knowledge of a wide variety of neutrino physics topics of interest and importance to the elementary-particle and nuclear-physics communities.

The quasielastic charged-current (CC) tau neutrino (antineutrino)-nucleus scattering is considered. The dependence of tau polarization on nuclear-structure effects is discussed in detail. The description of the nucleus is based on the Mean-Field Theory (MFT). The ground state of nucleus is described using the Relativistic Fermi Gas model (FG). The effective mass is introduced as well as the ring Random Phase Approximation (RPA) effects are taken into account in the framework of relativistic meson-nucleon model. The Local Density Approximation (LDA) is used for the argon nucleus, having in mind possible application to the ICARUS experiment. The discussion concentrates on the threshold region where the τ − can be unpolarized and the nuclear effects play an important role.
