KIMS-NaI is an experiment aimed at directly detecting Weakly Interacting Massive Particle (WIMP) via weak interactions with the nuclei in low-background NaI(Tl) crystals. Underground data for the WIMP search were obtained in the Yangyang underground laboratory with two NaI(Tl) crystals that have unprecedentedly high light-output. Since the scintillation characteristics of nuclear recoils from WIMP ... More

The AMoRE (Advanced Molybdenum based Rare process Experiment) phase-II is an experiment to search neutrino-less double beta decay of Mo-100 which is the later phase of the AMoRE experiment. If the double beta decay is found, it means that the neutrinos are Majorana particles and we can measure their masses. The experiment is going to be carried out in the deep underground in order to observe t ... More

There is a long-standing discrepancy between the neutron lifetime measured in beam and bottle experiments. We propose to explain this anomaly by a dark decay channel for the neutron, involving one or more dark sector particles in the final state. If any of these particles are stable, they can be the dark matter. We construct representative particle physics models consistent with all experimental ... More

We consider a model of decaying dark matter whose lifetime is comparable to the age of the universe. Its late decay to slightly lighter dark matter particle plus "non-interacting" particle can solve small scale problems. We will also show a smoking-gun signature of "non-interacting" particles from the dark matter decay.

We study how sterile neutrino with keV mass can be a dark matter candidate by proposing a new mechanism for the production of sterile neutrino in early universe. By estimating the average momentum of the sterile neutrino, we investigate whether sterile neutrinos can be warm dark matter or not. We briefly discuss how sterile neutrinos can be probed indirectly by using X-ray telescopes that can dete ... More

Searching for cosmic-origin rare new physics signals at Earth-surface-based detectors is usually challenging because of huge cosmic backgrounds. In order to avoid such a challenge, underground experiments are thus strongly motivated. If a signal of interest involves many features, however it becomes possible to isolate signal events from background ones. Along this line, I discuss boosted dark ... More

Our current understanding of the large-scale structure of the Universe is based on the cold dark matter model. Observed small-scale (sub-galactic) matter distribution, on the other hand, appears to challenge this standard paradigm. Self-interaction between dark matter particles reconciles small-scale issues by flattening the dark matter density profile inside halos. I will present a particle ph ... More

A dark gauge boson refers to a hypothetical gauge boson with a small mass and small coupling. Because of the small coupling, it could easily escape the existing experimental constraints, which is why it is called ‘dark’.
