Abstract:
To date, dark matter (DM) has only been observed through its gravitational interaction. Detection of a DM signal in an ultra-low background terrestrial detector will represent a ground-breaking discovery in physics and cosmology. The XENON collaboration has pioneered the development of liquid xenon time projection chambers and built a series of such detectors to search for DM particles. The XENONnT experiment is running at the INFN Gran Sasso National Laboratory in Italy, featuring a 6-tonne liquid xenon target and unprecedentedly low electronic recoil background. In this talk, I will present the first WIMPs search results from XENONnT.
Biography:
Prof. Gao Fei graduated from Shanghai Jiao Tong University with a Ph.D. in 2016. He then became a postdoctoral fellow and an associate research scientist at Columbia University before joining the Department of Physics of Tsinghua University in 2020. Prof. Gao's group at Tsinghua University is actively involved in the international XENON dark matter search experiment. Besides that, he and his collaborators also initiated the RELICS neutrino coherent scattering experiment in China. Since 2010, Prof. Gao has been developing a series of high-sensitivity liquid xenon detectors to search for unique and rare signals produced by dark matter and neutrinos. According to Google Scholar statistics, Prof. Gao has published more than 30 papers, including 15 Physical Review Letters, with more than 11,000 citations.
