Prof. Xiangdong Ji of Shanghai Jiao Tong University and University of Maryland, spokesperson of the PandaX Collaboration, announced new results on the dark matter (DM) search from the PandaX-II experiment on Monday Aug. 7, during the TeV Particle Astrophysics 2017 Conference at Columbus, Ohio, the United States. No DM candidate was identified within the data from an exposure of 54 ton-day, the largest reported DM direct detection data set to date. A world-leading 90% upper limit for the spin independent DM-nucleon cross section was set to be $6\times10^{-47}cm^{2}$ at the DM mass of $50 GeV/c^{2}$. Download the talk slides.
