The DAMIC-M experiment, led by Professor Paolo Privitera, has released new results on the search for dark matter particles with its prototype detector operating at the Modane Underground Laboratory in France. With an improvement of orders of magnitude in sensitivity with respect to any other detector technology, DAMIC-M new results exclude for the first time that dark matter may be primarily composed of hidden-sector particles with sub-GeV mass. The Chicago group played a leading role in the detector design, underground installation and commissioning, and data analysis.
