Fundamental Particle Physics with SWGO

The Southern Wide-field Gamma-ray Observatory (SWGO) is a proposed experiment that will continuously monitor the TeV gamma-ray sky. Similar to the High Altitude Water Cherenkov (HAWC) Observatory, it will have a wide field of view, nearly 100% duty cycle, and will therefore observe ~2/3 of the sky every day. It will use water Cherenkov detectors and be located in the Southern Hemisphere. SWGO is planned to be the most sensitive gamma-ray observatory in the Southern Hemisphere above ~10 TeV. SWGO will be able to perform several searches for physics beyond the Standard Model. Being located in the Southern Hemisphere will allow for searches for dark matter signals in key targets like the Galactic Center and newly discovered dwarf galaxies like Reticulum II. SWGO will also be able to search for primordial black holes, axion like particles, and Lorentz invariance violation.
