TL;DR: In this article, the PICASSO dark matter search experiment at SNOLAB was used to detect weakly interacting massive particles (WIMPs) with masses below 10 GeV/c 2.

TL;DR: The PICASSO experiment at SNOLAB as mentioned in this paper reported new results for spin-dependent WIMP interactions on 19F using the superheated droplet technique, and new features which enable background discrimination via the rejection of non-particle induced events are described.

TL;DR: The PICASSO collaboration observed for the first time a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids, which offers the possibility of improved background suppression and could be especially useful for dark matter experiments.

TL;DR: In this paper, the authors reported new results obtained in calibrations of superheated liquid droplet detectors used in dark matter searches with different radiation sources (n,$\alpha$,$\gamma$) in particular, detectors were spiked with alpha-emitters located inside and outside the droplets.
