Inclusive quasielastic charged-current neutrino-nucleus reactions

The quasielastic (QE) contribution of the nuclear inclusive electron scattering model developed by Gil, Nieves, and Oset [Nucl. Phys. A627, 543 (1997); A627, 599 (1997)] is extended to the study of electroweak charged current (CC) induced nuclear reactions, at intermediate energies of interest for future neutrino oscillation experiments. The model accounts for, among other nuclear effects, long...

Transport study of charged current interactions in neutrino-nucleus reactions

M. Kant and W. Cassing, Univ. of Giessen, Germany K. Langanke, GSI Darmstadt, Germany P. Vogel, California Institute of Technology, Pasadena, USA The interest in neutrino induced reactions has been rapidly increasing during the last decade while current and future long base-line (LBL) experiments, K2K, MiniBoone, MINOS, CERN-GS, J2K etc. aim at determining the electro-weak response of nucleons ...

Neutral-current neutrino reactions in the supernova environment

We study the neutral-current neutrino scattering for four nuclei in the iron region. We evaluate the cross sections for the relevant temperatures during the supernova core collapse and derive Gamow-Teller distributions from large-scale shell-model calculations. We show that the thermal population of the excited states significantly enhances the cross sections at low neutrino energies. Calculati...

Neutral current induced neutrino oscillations in a supernova

Neutral currents induced matter oscillations of electroweak-active (anti-)neutrinos to sterile neutrinos can explain the observed motion of pulsars. In contrast to a recently proposed explanation of the pulsar birth velocities based on the νμ,τ ↔ νe oscillations, the heaviest neutrino (either active or sterile) would have to have mass of order several keV. ∗ email address: [email protected] ...
