Abstract

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 3.3×104 kg day. Assuming a standard axial-vector spin-dependent WIMP interaction with Xe129 and Xe131 nuclei, the most stringent upper limits on WIMP-neutron cross sections for WIMPs with masses above 10 GeV/c2 are set in all dark matter direct detection experiments. The minimum upper limit of 4.1×10-41 cm2 at 90% confidence level is obtained for a WIMP mass of 40 GeV/c2. 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.
