| 英文摘要 | New constraints are presented on the spin-dependent weakly-interacting-massive- particle-(WIMP-) nucleon interaction from the PandaX-II experiment, using a data set corresponding to a total exposure of 3.3 x 10(4) kg day. Assuming a standard axial-vector spin-dependent WIMP interaction with Xe-129 and Xe-131 nuclei, the most stringent upper limits on WIMP- neutron cross sections for WIMPs with masses above 10 GeV/c(2) are set in all dark matter direct detection experiments. The minimum upper limit of 4.1 x 10(-41) cm(2) at 90% confidence level is obtained for a WIMP mass of 40 GeV/c(2). This represents more than a factor of 2 improvement on the best available limits at this and higher masses. These improved cross-section limits provide more stringent constraints on the effective WIMP- proton and WIMP- neutron couplings. |
