PICO: Current Status and Future Plans

The PICO collaboration employs bubble chambers filled with C$_{\mathrm{3}}$F$_{\mathrm{8}}$ to search for WIMP dark matter at the SNOLAB underground facility. Results from previous bubble chambers PICO-2L and PICO-60 provide the strongest constraints on spin-dependent WIMP-proton coupling. The next generation of PICO experiments includes PICO-40L, which was installed at SNOLAB in 2019, and PICO-500, currently being designed for a projected exposure on the scale of ton-years. This program is projected to improve WIMP-proton scattering sensitivity by an additional two orders of magnitude. I will report on the current status and future plans of these experiments.
