High Energy Experimental Physics Seminar- Dan Zhang UMD- "Dark Matter Search in PandaX-4T Commissioning Run"

PandaX-4T experiment searches for dark matter particles with a dual-phase time projection chamber holding 4 tonne liquid xenon in the sensitive volume. After the lab and detector construction for more than two years at China Jinping Underground Laboratory, PandaX-4T has begun to take scientific data since the end of the year 2020. In this talk, I will give an overview of the PandaX-4T hardwares and the weakly interacting massive particles (WIMPs) search with our commissioning data, including calibration, signal reconstruction and statistic inference for the limit and sensitivity settings.
