A profile-likelihood analysis shows the data to be consistent with a background-only hypothesis, setting new limits on spin-independent WIMP-nucleon cross-sections for WIMP masses above 9 GeV/c2. The most stringent limit is set at 30 GeV/c2 excluding cross sections above 5.9×10-48cm2 at the 90% confidence level.
