Low Energy Neutrino and Dark Matter Physics with the TEXONO + CDEX Research Programs

Abstract

The studies of neutrino physics and searches of Dark Matter are subjects at the frontiers of fundamental physics research. Many of the experimental techniques and facilities are common or related. The speaker will present the broad landscape of both subjects, as well as the evolution and experimental efforts pursued by the Taiwan-based TEXONO and China-based CDEX programs, using novel germanium ionization detectors with sub-keV sensitivities [1]. The experiments are performed at the Kuo-Sheng Reactor Neutrino Laboratory [2] near Taipei, the China Jinping Underground Laboratory [3] in Sichuan, and the forthcoming Sanmen Reactor Neutrino Laboratory in Zhejiang.

About the Speaker

Dr. Henry T. WONG is a particle physicist based in Taiwan. He grew up in Hong Kong, studied physics at the University of Oxford and the California Institute of Technology, has held junior research positions at the European Laboratory of Particle Physics (CERN) in Geneva, and is currently a Distinguished Research Fellow at the Institute of Physics, Academia Sinica, Taiwan.

Dr. Wong has played a pivotal role in the TEXONO Collaboration—a Taiwan-based international effort in neutrino and astroparticle physics research, in which the Kuo-Sheng Reactor Neutrino Laboratory is the flagship facility. He is also a founding partner in the CDEX dark matter searches program at the China Jinping Underground Laboratory. Dr. Wong and his collaborators have pioneered the use of germanium ionization detectors with sub-keV sensitivities in neutrino and dark matter researches.

Dr. Wong was elected as Fellows of the American Physical Society (2023) and of the Taiwan Physical Society (2017), and have garnered numerous academic research awards.
