摘要：
We present preliminary results from the second run of ZEPLIN-III, a two-phase xenon WIMP experiment which operated at the Boulby Mine (UK). The instrument was upgraded with low background photomultipliers; a new veto detector, featuring a tonne of plastic scintillator, was retrofitted around the WIMP target. Data from 319 days of science exposure rule out a scalar WIMP-nucleon cross-section above 4.2 x 10(-8) pb at 50 GeV/c(2) mass with 90% confidence.
