Uncovering the identity of dark matter, which makes up about 85% of the matter in the Universe, is among the most important goals of particle physics today. YITP faculty member Rouven Essig, in collaboration with Javier Tiffenberg (Fermilab), has received nearly $1-million from the Heising-Simons Foundation for the SENSEI experiment. SENSEI (Sub-Electron Noise Skipper-CCD Experimental Instrument) is a novel, ultra-sensitive, table-top direct-detection experiment that will search for two compelling classes of dark matter: Hidden-Sector Dark Matter with MeV-to-GeV masses and Ultralight Dark Matter with eV-to-keV masses. These two classes of dark matter are scientifically well-motivated but remarkably under-explored, and have been receiving increasing attention over the last few years.
