Unlocking the Deepest Mysteries of the Universe with a Deep Underground Liquid Xenon Observatory

Dark matter and neutrinos are among the most elusive neutral particles that permeate our Universe. The PandaX (Particle and Astrophysical Xenon) experiment, located in the China Jinping Underground Laboratory beneath a 2400-meter rock overburden, has been at the forefront of the search for dark matter particles for nearly two decades. As the sensitivity of the experiment continues to improve, the experiment has evolved into a versatile particle astrophysics observatory, with particular potentials on neutrino physics. In this talk, I will present the latest development in this field, and project the prospects of PandaX in the decades to come.

Biography: 
Jianglai Liu obtained his B. S. degree in Physics from Nanjing University in 1998. He received a Ph.D. degree in Physics in 2006 from the University of Maryland at College Park. He held a postdoctoral and then senior postdoctoral scholar position at Caltech from 2006 to 2010. He joined the School of Physics and Astronomy (SPA), Shanghai Jiao Tong University in 2011, and became a full professor in 2016. He serves as the Deputy Director of the Tsung-Dao Lee Institute (TDLI), and is a Hongwen Distinguished Professor jointly appointed between TDLI and SPA. He has worked on various experiments in the intersections of nuclear physics, particle physics, and astrophysics. He currently serves as the spokesperson of the PandaX experiment, a xenon-based dark matter and neutrino experiment at the China Jinping Underground Laboratory. He also has a strong involvement in the Daya Bay and JUNO experiments, studying the fundamental properties of neutrinos. He was awarded the Outstanding Junior Investigator from the National Natural Science Foundation of China in 2015. He received the Wang Ganchang Prize from the Chinese Physics Society and the Xplorer Prize from the Tencent Foundation (2019). Since 2023, he has been sponsored as a New Cornerstone Investigator (www.newcornerstone.org.cn).
