Sources of Low-Energy Events in Low-Threshold Dark-Matter and Neutrino Detectors

Coherent neutrino scattering in dark matter detectors

Low Energy Atmospheric Neutrino Events in MACRO

The flux of low energy atmospheric neutrinos (Eν ∼ 4 GeV ) has been studied with the MACRO detector at Gran Sasso by detecting νμ interactions inside the apparatus, and by upward-going stopping muons. The updated analysis of the data collected until now with the complete apparatus will be presented. The results show a deficit of the measured number of events in an uniform way over the whole zen...

Testing Dark Matter with Neutrino Detectors

Neutrinos are the least detectable Standard Model particle. By making use of this fact, we consider dark matter annihilations and decays in the galactic halo and show how present and future neutrino detectors could be used to set general limits on the dark matter annihilation cross section and on the dark matter lifetime.

Towards low-threshold, real-time solar neutrino detectors

We discuss an alternative approach to the detection of solar neutrinos using a coarsely segmented detector based on inverse-beta decay onto 160Gd or 176Yb. While it is known that similar approaches, already discussed in the literature, can in principle provide low-threshold, real-time energy spectroscopy with intrinsic background rejection features, the concepts presented here make this scheme ...

Supernova pointing with low- and high-energy neutrino detectors

A future galactic SN can be located several hours before the optical explosion through the MeV-neutrino burst, exploiting the directionality of n-e scattering in a water Cherenkov detector such as Super-Kamiokande. We study the statistical efficiency of different methods for extracting the SN direction and identify a simple approach that is nearly optimal, yet independent of the exact SN neutri...
