| contents | Supernova neutrino boosted dark matter (SN$ν$ BDM) and its afterglow effect have been shown to be a promising signature for beyond Standard Model (bSM) physics. The time-evolution feature of SN$ν$ BDM allows for %the possibly direct inference of DM mass $m_χ$, and results in significant background suppression with improving sensitivity. This paper extends the earlier study and provides a general framework for computing the SN$ν$ BDM fluxes for a supernova that occurs at any location in our galaxy. A bSM $U(1)_{L_μ-L_τ}$ model with its gauge boson coupling to both DM and the second and third generation of leptons is considered, which allows for both DM-$ν$ and DM-$e$ interactions. Detailed analysis of the temporal profile, angular distribution, and energy spectrum of the SN$ν$ BDM are performed. Unique signatures in SN$ν$ BDM allowing extraction of $m_χ$ and detail features that contain information of the underlying interaction type are discussed. Expected sensitivities on the above new physics model from Super-Kamiokande, Hyper-Kamiokande, and DUNE detections of BDM events induced by the next galactic SN are derived and compared with the existing bounds. |
