Abstract

Astronomical and cosmological observations in the past 100 years have shown that a large fraction of the universe is made up with invisible dark matter. However, there has been no direct detection of dark matter particles. Breakthrough in this area is likely to be revolutionary. At the world’s deepest underground laboratory, the China Jinping Laboratory, is an ideal location for dark matter experiments. One of the experiment at Jinping, the PandaX xenon experiment，led by SJTU, has reached the forefront in detection sensitivity. In this talk, I will introduce the past, present and future of this experiment.

Bio

Professor Liu obtained B. S. in Physics from Nanjing University in 1998. He received Ph.D. degree in Physics in 2006 from the University of Maryland at College Park, USA. He held postdoctoral then senior postdoctoral scholar position at Caltech from 2006 to 2010. He joined SJTU as a distinguished research fellow in 2011, and became a full professor in 2016.

He has worked on various experiments in the intersections of nuclear, particle, and astrophysics. 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 is now the PI of the underground physics group at SJTU, with interests centered on the dark matter and neutrino physics. He currently serves as the spokesperson of the PandaX experiment, a xenon-based direct dark matter search at the China Jin-Ping Underground Laboratory. He also has strong involvements in the Daya Bay and JUNO experiments, studying the fundamental properties of the neutrinos.

Liu received the best Ph.D. dissertation prize from Thomas Jefferson Lab in 2006. He was awarded the Outstanding Junior Investigator from NSFC in 2015. In 2019, he received the Wang Ganchang Prize of the Chinese Physics Society and the Xplorer Prize of the Tencent Foundation for his contributions to the studies of dark matter and neutrino properties in the PandaX and Daya Bay experiments.
