Abstract
In this paper, the performances of Borexino as a Supernova neutrino detector are analyzed and discussed. The expected neutrino signal from a typical Type II Supernova at a distance of 10 kpc is calculated: a burst of around 240 events would appear in Borexino within a time interval of about 10 s. Most of these events would come from the reaction channels ¯νe + p → e+ + n and ν + p → ν + p, while about 30 events would be induced by the interaction of the Supernova neutrino flux on 12C in the liquid scintillator: for most of these reactions, Borexino features unique detection capabilities, thanks to its low-energy sensitivity, ultra-low radioactive background and large homogeneous volume. The possibility to tag and identify the different neutrino detection reactions gives access to key information concerning Supernova physics and non-standard neutrino properties. The detection of neutrinos via elastic scattering off protons in Borexino is discussed here for the first time: this reaction is proven to be a powerful component of the neutrino-induced burst of events. Finally, a viable “Supernova trigger” condition is established, which allows to detect a Supernova explosion up to a distance of 63 kpc.
