Supernova Neutrino Detection in LZ

Abstract

In the first 10 seconds of a core-collapse supernova, almost all of its progenitor's gravitational potential, O(10${}^{53}$~ergs), is carried away in the form of neutrinos. These neutrinos, with O(10~MeV) kinetic energy, can interact via coherent elastic neutrino-nucleus scattering (CE$\nu$NS) depositing O(1~keV) in detectors. In this work, we demonstrate that low-background dark matter detectors, such as LUX-ZEPLIN (LZ), optimized for detecting low-energy depositions, are capable of detecting these neutrino interactions. For instance, a 27~M${}_{\odot }$ supernova at 10~kpc is expected to produce $\sim$350 neutrino interactions in the 7-tonne liquid xenon active volume of LZ. Based on the LS220 EoS neutrino flux model for a SN, the Noble Element Simulation Technique (NEST), and predicted CE$\nu$NS cross-sections for xenon, to study energy deposition and detection of SN neutrinos in LZ. We simulate the response of the LZ data acquisition system (DAQ) and demonstrate its capability and limitations in handling this interaction rate. We present an overview of the LZ detector, focusing on the benefits of liquid xenon for supernova neutrino detection. We discuss energy deposition and detector response simulations and their results. We present an analysis technique to reconstruct the total number of neutrinos and the time of the supernova core bounce.
