Abstract

Dark matter is a hypothetical form of matter that, if it exists, may account for more than a quarter of the energy density of our universe. Despite the variety of astrophysical evidence pointing to its existence, the direct interaction of dark matter in a terrestrial detector is yet to be observed. The Super Cryogenic Dark Matter Search (SuperCDMS) experiment tries to observe a dark matter signal in silicon and germanium detectors operated around 50 miliKelvin. In this talk, I will discuss the status of the next generation SuperCDMS experiment, the recent results with an eV-resolution gram-scale prototype detector, and the future plan with this technology.
