Inclusive charged-current neutrino-nucleus reactions calculated with the relativistic quasiparticle random-phase approximation
- Physics Department, Faculty of Science, University of Zagreb (Croatia)
Inclusive neutrino-nucleus cross sections are calculated using a consistent relativistic mean-field theoretical framework. The weak lepton-hadron interaction is expressed in the standard current-current form, the nuclear ground state is described with the relativistic Hartree-Bogoliubov model, and the relevant transitions to excited nuclear states are calculated in the relativistic quasiparticle random-phase approximation. Illustrative test calculations are performed for charged-current neutrino reactions on {sup 12}C, {sup 16}O, {sup 56}Fe, and {sup 208}Pb, and results compared with previous studies and available data. Through the use of the experimental neutrino fluxes, the averaged cross sections are evaluated for nuclei of interest for neutrino detectors. We analyze the total neutrino-nucleus cross sections and the evolution of the contribution of the different multipole excitations as a function of neutrino energy. The cross sections for reactions of supernova neutrinos on {sup 16}O and {sup 208}Pb target nuclei are analyzed as functions of the temperature and chemical potential.
