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

TL;DR: PICASSO at SNOLAB searches primarily for spin-dependent WIMP interactions on 19F using the superheated droplet technique as discussed by the authors, which is based on the bubble chamber principle.
