Data-Driven Modeling of Electron Recoil Nucleation in PICO C_3F_8 Bubble Chambers

The primary advantage of moderately superheated bubble chamber detectors is their simultaneous sensitivity to nuclear recoils from WIMP dark matter and insensitivity to electron recoil backgrounds. A comprehensive analysis of PICO gamma calibration data demonstrates for the first time that electron recoils in C_3F_8 scale in accordance with a new... Show more
