Description
The PandaX-4T experiment will utilize a two-phase liquid/gas xenon time projection chamber to search dark matter. The PandaX-4T is located in the Hall B2 of the Jinping Underground Laboratory with 2400 m overburden. In the commissioning run, 1058 candidate events are identified with 3.7-tonne of liquid xenon target and an exposure of 0.63 tonne·year. A stringent limit to the dark matter-nucleon spin-independent interactions is set with a lowest excluded cross section (90% C.L.) of $3.8 \times 10^{-47}$ cm$^2$ at a dark matter mass of 30 GeV/c2. An details of the detector performance and data analysis will be presented in this talk.
