KIM Yeongduk began the KIMS (Korea Invisible Mass Search) project to search the dark matter directly and is representing KIMS group since 2012. He has also actively participated in the neutrino oscillation experiment (RENO), which has successfully measured the 3rd mixing angle of the neutrinos. He is also interested in the neutrinoless double beta decay using scintillating crystals, and is a executive member of AMoRE experiment.
We now know that neutrinos are massive. But we do not know their absolute masses nor their natures. Discovering these important unknowns can be related to leptogenesis theories that make attempts to explain particle-antiparticle asymmetry in the universe. Neutrinoless double beta decay experiment is the most practical approach for determining the absolute masses and understanding the nature of neutrinos. We, the Center for Underground Physics (CUP) at the IBS, will perform several phases of AMoRE (Advanced Mo-based Rare process Experiment) experiments that probe the neutrino mass down to 0.03 eV.
Advancing our knowledge of dark matter is necessary in order to understand the origin and structure of the universe, because the universe consists of 26.8% dark matter and 68.3% dark energy. We are running experiments to search directly for WIMPs (Weakly Interacting Massive Particles), which offer the most plausible explanation as to the nature of dark matter. We will develop new detection techniques to search for dark matter, which would provide more sensitive than current running experiments.
We will install detectors with ultra-low noises at about 700 meter-deep underground laboratory in Yangyang in Korea to reduce cosmic ray backgrounds for searching extremely rare events such as neutrinoless double beta decays, dark matter and etc. Since we expect to see only a handful of signal events in a year, the success of the experiments highly relies on reducing backgrounds. We will achieve our goal by growing ultra-low background crystals and by developing low-temperature sensors that have excellent energy resolution and the power to distinguish the signals from huge background events.
