6. CPNR 5 - e-mu colliders and discovery of heavy sterile neutrinos.

Prof. 충선 김

5/22/26, 1:00 PM

조만간 미국에서 시도하고자 하는 뮤온충돌기 (muon collider) 를 응용하여 가능한 실험에 대해 연구하였다.
전자-뮤온 충돌실험 (e-mu collider)을 이용하여 표준모형을 넘어서는 전하를 띤 경입자의 맛깔 비보존 변환 과정 (charged Lepton Flavor Violation -cLFV)을 측정함으로서 무거운 불활성 중성미자 (heavy Sterile Neutrino)의 발견에 대한 이론을 설명하고자 한다.

7. CPNR 6: 2D Ising model sampling using D-Wave quantum annealer

Dr 순규 이

5/22/26, 2:00 PM

D-Wave uses so-called a quantum annealing process to solve problems of certain categories rather than universal quantum computers do. This research applies D-Wave quantum annealer to find ground state configurations of 2D Ising model. Due to its limitation in the number of qubits, D-Wave is used to update configuration of smaller sized sub-lattice, such as 4 by 4 etc., not of a whole 2D...

8. CPNR 7: Water-based Liquid Scintillator R&D effort at Brookhaven National Laboratory

Dr 순우 권

5/22/26, 2:30 PM

Water-based Liquid Scintillator (WbLS) is an innovative material for constructing large-scale detectors in neutrino and dark matter research. This innovative material features a tunable light yield, facilitated by an inline circulation system, which permits adaptable detector optimization tailored to various physics searches. At Brookhaven National Laboratory (BNL), both 1-ton and 30-ton scale...

9. CPNR 8: Fundamentals of HPGe Detectors: A Metrological Approach to High-Resolution Gamma-Ray Spectroscopy

Dr 상용 김

5/22/26, 3:00 PM

High-Purity Germanium (HPGe) detectors remain the absolute gold standard for high-resolution gamma-ray spectroscopy across diverse disciplines in experimental physics. Rather than focusing solely on solid-state physics theory, this presentation provides a comprehensive overview of the fundamental metrological principles governing practical HPGe detector operations. We will systematically...

15. OMEG 4 - Multipole-Resolved Nuclear Transition Strengths of 12C Induced by Mono-Energetic KDAR Neutrinos

Mr 채윤 이

5/22/26, 4:00 PM

This study investigates charged-current (CC) neutrino-induced reactions on $^{12}\text{C}$ using mono-energetic neutrinos ($E_\nu = 236$ MeV) from kaon decay at rest (KDAR). We performed a detailed decomposition of nuclear transition strengths into spin-parity states, longitudinal and transverse components, and vector and axial-vector contributions. Our results demonstrate that KDAR neutrinos...

16. OMEG 5 - Production of strange and charmed vector mesons in meson-induced reactions

Dr 상호 김

5/22/26, 4:30 PM

We investigate the reaction mechanisms of the strangeness-production processes K- p -> ϕY and π-p -> KY within a hybrid Regge framework, including the t-channel K- and K-Reggeon exchanges. We present results for the total cross sections, t-dependent differential cross sections, and
spin-density matrix elements (SDMEs), and compare them with the available experimental data. To obtain...

10. Invited Speakers III - JSNS2/-II

Prof. 명렬 박

5/22/26, 5:00 PM

The JSNS2 (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) experiment and its upcoming Phase-II upgrade present a compelling frontier in neutrino physics, uniquely positioned to test the eV-scale sterile neutrino anomaly. Rather than relying solely on theoretical phenomenology, this presentation focuses on the experimental mechanics and the unique beam characteristics that...
