About the Lab
Professor Soobong Kim's research lab specializes in neutrino physics, with a primary focus on reactor neutrino oscillations and the search for sterile neutrinos. The lab leads the RENO experiment at the Hanbit nuclear power plant in Korea, conducting precise measurements of the neutrino mixing angle θ₁₃ and effective mass-squared difference Δmₑₑ² using high-statistics data from near and far detectors. The lab also contributes to the JSNS² experiment at J-PARC, investigating short-baseline neutrino anomalies through advanced detector technologies, including acrylic vessels for anti-neutrino detection. In parallel, the lab explores data governance and information security in emerging data economies, particularly in financial data trading ecosystems.

5The RENO experiment has analyzed about 500 live days of data to observe an energy dependent disappearance of reactor ν[over ¯]_{e} by comparing their prompt signal spectra measured in two identical near and far detectors. In the period between August of 2011 and January of 2013, the far (near) detector observed 31 541 (290 775) electron antineutrino candidate events with a background fraction of 4.9% (2.8%). The measured prompt spectra show an excess of reactor ν[over ¯]_{e} around 5 MeV relativ
The RENO experiment reports more precisely measured values of θ_{13} and |Δm_{ee}^{2}| using ∼2200 live days of data. The amplitude and frequency of reactor electron antineutrino (ν[over ¯]_{e}) oscillation are measured by comparing the prompt signal spectra obtained from two identical near and far detectors. In the period between August 2011 and February 2018, the far (near) detector observed 103 212 (850 666) ν[over ¯]_{e} candidate events with a background fraction of 4.8% (2.0%). A clear ene
데이터 경제시대 속에서 활발한 데이터 유통환경을 조성하고자 다양한 정책들이 시행되고 있다. 국내에서는 공공주도 데이터 거버넌스 아래 금융데이터거래소의 출범을 시작으로 빅데이터 유통 플랫폼 형성과 데이터 거래가 시작되었다. 주요 데이터 선진국들의 경우, 오래전부터 데이터브로커 산업을 바탕으로 데이터 유통환경을 구축해왔고, 그로부터 산출되는 부가가치들을 통해 국가 데이터 경쟁력을 강화해왔다. 그런데 데이터브로커를 통해 이루어지는 활발한 데이터 유통의 이면에는 수많은 정보보호 이슈들이 존재하고, 이로 인해 다양한 프라이버시 문제와 국가 안보적 위협들이 발생하였다. 이러한 문제들은 국내 금융데이터 거래 과정에서도 충분히 발생할 수 있다. 본 연구에서는 데이터브로커로 인해 발생한 데이터 거래의 정보보호 이슈를 살펴보고, 정보보호의 관점에서 데이터 거래 시 고려해야 할 사항들을 도출하였다. 이후, 정보보호 고려사항들이 국내 금융데이터거래소 거래단계별 정보보호 정책에 잘 반영되어 있는지 검증해보
We report an updated neutrino mixing angle of $θ_{13}$ obtained from a complete data sample of the RENO experiment. The experiment has measured the amplitude and frequency of reactor anti-electron-neutrinos ($\barν_{e}$) oscillations at the Hanbit nuclear power plant, Younggwang, Korea, since August 2011. As of March 2023, the data acquisition was completed after a total of 3800 live days of detector operation. The observed candidates via inverse beta decay (IBD) are 1,211,995 (144,667) in the n
The JSNS$^{2}$ (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) is an experiment designed for the search for sterile neutrinos. The experiment is currently at the stage of the second phase named JSNS$^{2}$-II with two detectors at near and far locations from the neutrino source. One of the key components of the experiment is an acrylic vessel, that is used for the target volume for the detection of the anti-neutrinos. The specifications, design, and measured properties of the
