Abstract

The PICO collaboration reports results obtained by PICO-2L Run-2 after carefully controlling for particulate contamination. The data clearly indicates that previously observed anomalies were due to contamination in the bubble chamber fluid. These observations set new bounds on spin-dependent scattering of dark matter, and help pave the way for larger scale experiments.
