Spin-Dependent Weakly-Interacting-Massive-Particle–Nucleon Cross Section Limits from First Data of PandaX-II Experiment
Spin-Dependent Weakly-Interacting-Massive-Particle–Nucleon Cross Section Limits from First Data of PandaX-II Experiment
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 …
