Improved Limits on Spin-Dependent WIMP-Proton Interactions from a Two Liter CF${}_3$I Bubble Chamber

Abstract

Data from the operation of a bubble chamber filled with 3.5 kg of CF${}_3$I in a shallow underground site are reported. An analysis of ultrasound signals accompanying bubble nucleations confirms that alpha decays generate a significantly louder acoustic emission than single nuclear recoils, leading to an efficient background discrimination. Three dark matter candidate events were observed during an effective exposure of 28.1 kg-day, consistent with a neutron background. This observation provides the strongest direct detection constraint to date on WIMP-proton spin-dependent scattering for WIMP masses $>20$ GeV/c${}^2$.
