Description
In this talk, we review boosted dark matter (BDM) production mechanisms via extended dark sectors and charged cosmic rays. Next, we propose a novel dark-matter boosting mechanism by cosmic-ray neutrinos. The new mechanism is so significant that the arriving flux of cosmic-ray neutrino BDM (νBDM) lighter than O(1-10) MeV on Earth is substantially larger than the one of the cosmic-ray electron BDM. Therefore, νBDM can dominantly contribute in direct detection experiments. We derive conservative but still stringent bounds and future sensitivity limits for νBDM from advanced underground dark matter and neutrino experiments such as XENON1T/nT and JUNO.
