Recent Results from the SIMPLE Dark Matter Search

Abstract

SIMPLE is an experimental search for evidence of spin-dependent dark matter, based on superheated droplet detectors using C${}_2$ClF${}_5$. We report preliminary results of a 0.6 kgdy exposure of five one liter devices, each containing $\sim$10 g active mass, in the 1500 mwe LSBB (Rustrel, France). In combination with improvements in detector sensitivity, the results exclude a WIMP--proton interaction above 5 pb at M${}_{\chi }$ = 50 GeV/c${}^2$.
