Title
Detection of Light and Ultralight Dark Matter Particles with the TESSERACT Experiment
Abstract
Identifying dark matter particles remains a major goal in physics, with recent models suggesting masses below 1 GeV/c². The TESSERACT experiment will search for light and ultra-light dark matter using sub-eV threshold detectors, targeting masses down to 10 MeV via nuclear and electron recoils. It will combine multiple materials—superfluid helium, polar and scintillating crystals, and cryogenic silicon/germanium—for background rejection and recoil discrimination. Two shielded cryostats at the Laboratoire Souterrain de Modane will host the detectors, with underground operations starting in 2029. I will also present recent results from surface prototype tests.
