Abstract

The PICASSO (Project In Canada to Search for SuperSymetric Object) experiment is searching for cold dark matter (CDM) through the direct detection of weakly interacting massive particles (WIMPs), in particular neutralinos (x) via their spin-dependent interactions with nuclei. The experiment is taking data in the Sudbury Neutrino Observatory Laboratory at a depth of 2070 m (6000 mwe). PICASSO uses a liquid fluorocarbon, C4F10 as the active material and searches for WIMP interactions on 19F. Measured limits on the spin-dependent x-proton and x-neuh"011 CT0SS sections are presented and compared with results from other experiments. Excluded regions in the plane of the effective x-proton and x-neutron coupling strengths ap and a, are also reported. The next phases of PICASSO are presented. They will involve detectors of larger volume and increased active mass with higher sensitivity in the spin-dependent sector.
