英文摘要 | The PandaX-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Un- derground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4:9 x 10(-5) kg(-1)d(-1)keV(-1). The nuclear recoil background in the same region is 2:8 x 10(-7) kg(-1)d(-1)keV(-1). With an exposure of 5.6 ton-years, the sensitivity of PandaX-4T could reach a minimum spin-independent dark matter-nucleon cross section of 6 x 10(-48) cm(2) at a dark matter mass of 40 GeV/c(2). |
