Abstract
Ton-scale direct dark matter search experiments should be sensitive to neutrino-induced recoil events from either 8B solar neutrinos or the brief but intense flux from a core collapse supernova in the Milky Way. These low-threshold detectors are sensitive to the very low recoil energies, of order 10âkeV, deposited via coherent elastic scatters between supernova neutrinos and target nuclei. Large superheated fluid detectors like PICO-500, a bubble chamber to be initially filled with an active target of 1ât of C3F8, should see multiple-bubble events from CEνNS if the detector is live during a neutrino burst from a supernova at a distance up to 10âkpc. This paper discusses conditions under which bubble chambers could be used as an independent measurement in the event of a supernova similar to SN 1987A, with particular sensitivity to the currently less-constrained heavy-lepton νx channel.
