Astronomy Colloquium (22.02/2023)：Unlocking the mysteries of dark matter and neutrinos with a deep underground xenon observatory
Description
Title: Unlocking the mysteries of dark matter and neutrinos with a deep underground xenon observatory
Speaker：Jianglai Liu (SJTU)
Abstract: Dark matter and neutrinos are elusive neutral matter filling up our Universe. The PandaX (Particle and Astrophysical Xenon) experiment, located in the world’s deepest China Jinping Underground Laboratory, is dedicated to searching for dark matter particles and studying the fundamental properties of neutrinos. The current running experiment, PandaX-4T, contains a sensitive time-projection-chamber with a 3.7-ton liquid xenon target. In this talk, after an overview, I will present recent results from PandaX-4T in dark matter direct detection, double beta decay of 136Xe, as well as solar neutrinos. I will also discuss the future prospects of PandaX.

Jianglai Liu has worked on various experiments in the intersections of nuclear physics, particle physics, and astrophysics. His current research focuses on dark matter and neutrinos, and serves as the spokesperson of the PandaX experiment. He has also been strongly involved in the Daya Bay and JUNO experiments. In his earlier career, he studied the strange quark form factors of the nucleon at the Thomas Jefferson National Accelerator Facility (TJNAF) via parity-violating electron scattering (G-zero, 1999-2006), and performed measurements of the axial-vector coupling constant of the nucleon using ultracold neutron decays at the Los Alamos National Laboratory (UCNA, 2006-2010). He received the Outstanding Young Researcher award from NSFC in 2015, and is the recipient of the Wang Ganchang Prize from the Chinese Physics Society and the Xplorer Prize from the Tencent Foundation in 2019.
