Scattering Cross Sections

Inelastic neutrino-nucleus scattering cross sections at low and intermediate energies are investigated for currently interesting nuclei employed in neutrino-detection experiments. This is an extension to charged current processes of our previous QRPA calculations referred to neutral current neutrino/antineutrino-nucleus reactions. Our preliminary results for the reactions 56Fe(νe, e−)56Co and 40Ar(νe, e−)40K compare rather well with similar calculations obtained in the context of continuum RPA.

Scattering Cross Sections

At first, we evaluate scattering cross sections of low, and intermediate-energy neutrinos scattered off the114Cd isotope, the most abundant Cd isotope present also in the COBRA detector (CdTe and CdZnTe materials) which aims to search for double beta decay events and neutrino observations at Gran Sasso laboratory (LNGS). The coherentν-nucleus channel addressed here is the dominant reaction channel of the neutral currentν-nucleus scattering. Ourν-nucleus cross sections (calculated with a refinement of the quasiparticle random-phase approximation, QRPA) refer to thegs→gstransitions forν-energiesεν≤100 MeV. Subsequently, simulatedν-signals on114Cd isotope are derived. Towards this purpose, the required folded cross section comes out of simulation techniques by employing several low, and intermediate-energy neutrino distributions of the astrophysicalν-sources, like the solar, supernova, and Earth neutrinos, as well as the laboratory neutrinos, the reactor neutrinos, the pion-muon stopped neutrinos, and theβ-beam neutrinos.

The Cross

We present the neutral-current (NC) and charged-current (CC) reactions by incident neutrino (antineutrino) scattering on the nucleon, and also on the 12 C target in quasi-elastic region within the framework of a relativistic single particle model. Effects of the strangeness are studied on the cross sections, the ratios between the NC and CC reactions, and the asymmetries. We found that there exists some cancellation of the strange quark contributions between the knocked-out protons and neutrons in the neutrino (antineutrino)-nucleus scattering. The effect of the strangeness on the asymmetry exhibits larger than that on the ratio and the cross section.

Scattering Cross Sections

Neutrino(antineutrino)–deuteron elastic and neutral current breakup processes are studied to provide information about the structure of the weak hadronic neutral currents. The scattering cross sections for these processes have been calculated with the help of the impulse approximation. Thus, we have additional input for the determination of the weak hadronic neutral current couplings. Some of the popular models can be put to test as they give distinguishable predictions for these processes. Also since the deuterium filled bubble chambers will be exposed to neutrino beams, our results may serve as a guide as to what to expect theoretically.
