Speaker：

Liangjian Wen, a professor at the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, has long been engaged in neutrino physics and experimental research. He participated in the Daya Bay Reactor Neutrino Experiment and is currently conducting research on neutrino oscillations, astrophysical neutrinos, and future neutrinoless double-beta decay (0νββ) experimental techniques as part of the Jiangmen Underground Neutrino Observatory (JUNO), where he serves as the chair of Analysis Coordination Committee. He is also involved in the U.S.-based nEXO experiment, which seeks to detect the 0νββ process of 136Xe. Supported by the National Science Fund for Distinguished Young Scholars, he has received numerous accolades, including the Young Scientist Prize from the IUPAP Commission on Particles and Fields, the Chinese Academy of Sciences Young Scientist Award, and the Xplorer Prize.

Abstract:

Neutrinos are one of the fundamental building blocks of matter, and their non-zero mass lies beyond the Standard Model of particle physics. Determining the neutrino mass ordering and precisely measuring the absolute mass are crucial for uncovering the origin of neutrino mass, understanding the early evolution of the universe, and the formation of its structure. Additionally, as a candidate for Majorana fermions, confirming the Majorana nature of neutrinos could have implications for fundamental research in particle physics and cosmology. This includes testing the conservation of lepton number, determining necessary modifications to the Standard Model, and providing new pathways to address the mystery of the universe's matter-antimatter asymmetry. On December 18, 2024, Xinhua News reported the filling of liquid in the Jiangmen Underground Neutrino Observatory (JUNO). This talk will present a brief review on experimental neutrino physics and the latest advancements in this cutting-edge experiment studying neutrino mass and other fundamental physics.
