Abstract / Description of output
The NAIAD experiment (NaI Advanced Detector) for WIMP dark matter
searches at the Boulby Underground Laboratory (North Yorkshire, UK) ran
from 2000 until 2003. A total of 44.9 kg × years of data collected
with 2 encapsulated and 4 unencapsulated NaI(Tl) crystals with high
light yield were included in the analysis. We present final results of
this analysis carried out using pulse shape discrimination. No signal
associated with nuclear recoils from WIMP interactions was observed in
any run with any crystal. This allowed us to set upper limits on the
WIMP-nucleon spin-independent and WIMP-proton spin-dependent
cross-sections. The NAIAD experiment has so far imposed the most
stringent constraints on the spin-dependent WIMP-proton cross-section.
