Description

Supernova neutrino boosted dark matter (SNν BDM) and its afterglow effect stand as promising signatures for exploring beyond Standard Model (bSM) physics. The unique time-evolution feature of SNν BDM offers a direct avenue for inferring DM mass, concurrently leading to substantial background reduction with increasing sensitivity. In this talk, I will expound upon the SNν BDM framework applicable to next supernovae occurring anywhere in our galaxy, emphasizing its distinctive signatures that facilitate DM mass extraction. Additionally, I will present anticipated sensitivities on DM-ν and DM-e cross sections, derived from experiments including Super-Kamiokande, Hyper-Kamiokande, and DUNE, and compare these projected results with existing constraints
