Primordial Black Hole Hotspots Beyond Flat Spacetime
Doojin Kim, TaeHun Kim, Jong-Chul Park +1
Light primordial black holes heat the surrounding plasma via Hawking radiation, forming localized hotspots whose temperature may far exceed that of the cosmological background. Pre…
Extracting Dark-Matter Mass from Angular Scanning
Daeyeong Jeong, Doojin Kim, Jong-Chul Park
We propose a novel method to determine the mass scale of ambient dark matter, applicable to (at least effectively) two-dimensional direct detection experiments that allow for direc…
Prospects for Light Dark Matter Searches at Large-Volume Neutrino Detectors
Bhaskar Dutta, Wei-Chih Huang, Doojin Kim +3
We propose a new approach to search for light dark matter (DM), with keV-GeV mass, via inelastic nucleus scattering at large-volume neutrino detectors such as Borexino, DUNE, Super…
Beam-Dump Ceiling and Its Experimental Implication: The Case of a Portable Experiment
Doojin Kim, Jaehoon Yu, Jong-Chul Park +1
We generalize the nature of the so-called beam-dump ``ceiling'' beyond which the improvement on the sensitivity reach in the search for fast-decaying mediators dramatically slows d…
