Searching for supernova neutrinos with dark matter detectors

Abstract

Large underground detectors, aimed at the search of rare processes, have the potential to contribute to the study of the next galactic supernova, by means of the study of neutrino-induced nuclear recoils. However, it is necessary to achieve continual sensitivity to the region of very low energies, above ∼ keV. An external trigger can be extremely valuable in this respect. The cases of off-line and on-line triggers are considered, making reference, respectively, to the existing SNEWS network and to a by-product of the operations of the LVD detector: the size of the memory buffer for temporary data storage, necessary in these two cases, is estimated.
