Limits on spin-dependent WIMP-nucleon cross-sections from the first ZEPLIN-II data

Abstract : The first underground data run of the ZEPLIN-II experiment has set a limit on the nuclear recoil rate in the two-phase xenon detector for direct dark matter searches. In this Letter the results from this run are converted into the limits on spin-dependent WIMP-proton and WIMP-neutron cross-sections. The minimum of the curve for WIMP-neutron cross-section corresponds to 7×10 pb at a WIMP mass of around 65 GeV.
