Neutrino interactions with carbon: recent measurements and a new test of universality

On the importance of low-energy beta beams for supernova neutrino physics

“…Comparison between the original and the synthetic spectra for a neutrino energy distribution with average energy ε = 18 MeV and α = 3. In the top panel, the curves to the left represent the spectra, the curves to the right of the plot show total folded cross-sections for neutral-current neutrino scattering off 16 O. For each set of curves, the full line represents results obtained with the original spectrum, while the other shows the results for calculations with three (dashed) and five (dotted) beta-beam spectra in the fit.…”

“…2. There we show the original power law spectra, together with the N = 3 and N = 5 fits, and the respective folded cross-sections for neutralcurrent scattering off 16 O as a function of incident neutrino energy. The figure clearly illustrates that the folded cross-section reaches its main strength for neutrinos in the high-energy part of the distribution.…”

“…Galactic supernova neutrinos could be detected by existing and proposed supernova neutrino detectors such as SNO [9], SuperKamiokande [10], KamLAND [1], LVD [11], MiniBooNe [12], OMNIS [13], LAND [14], and LENA [15]. Favored detection nuclei are 12 C, 16 O, 56 Fe, 208 Pb, and deuterium. However, the signal in the detector can only be interpreted as well as the relevant neutrino-nucleus cross-sections are understood.…”

“…region. This is due to the very small cross-sections for weak-interaction processes, and an additional limitation is caused by the fact that monochromatic neutrino beams are not available [16,17]. This has as a consequence that for most applications one has to rely on theoretical predictions, with their related uncertainties and model dependencies [18].…”
