XENONnT Dark Matter Detector Challenges Quantum Collapse Theories
The XENONnT dark matter detector, located at the INFN Gran Sasso National Laboratory in Italy, has been used to test theories of quantum collapse, specifically the Continuous Spontaneous Localization (CSL) and Diòsi–Penrose models. These models predict that spontaneous quantum collapse would emit faint X-ray radiation, which the XENONnT detector is capable of detecting. Recent analyses of data collected by the detector have challenged these models, as no evidence of the predicted X-ray bursts was found. This experiment, conducted by a collaboration of theoretical physicists and experimentalists, has set the strongest limits to date on the parameters of these quantum collapse models.
