Abstract: (APS)
In this Letter, we report the dark matter search results from the commissioning run (Run0) and the first science run (Run1) of the PandaX-4T experiment. The two datasets were processed with a unified procedure, with the Run1 data treated blindly. The data processing is improved compared to previous work, unifying the low-level signal reconstruction in a wide energy range up to 120 keV. With a total exposure of , no significant excess of nuclear recoil events is found. The lowest 90% confidence level exclusion on the spin-independent cross section is at a dark matter mass of . Our results represent the most stringent constraint for a dark matter mass above .Note:
