Scientific paper

Current spin-dependent WIMP searches are analyzed within the model-independent framework of Tovey et al., which itself is extended to the case of positive signal experiments. The results indicate the need of combining experiments with different neutron-to-proton group spin ratios in order to obtain, for a given WIMP mass, reduced allowed areas in the spin-dependent WIMP-proton, WIMP-neutron cross section plane. In the sample survey presented here, and in the case of null signal experiments, these derive from NAIAD and ZEPLIN I, yielding, for a WIMP mass of 50 GeV, σn ≤ 0.18, σp ≤ 0.7 pb; confirmation of the DAMA/NaI results would imply σn ≤ 0.17, 0.01 ≤ σp ≤ 0.29 pb.
