Testing quantum collapse theory with the XENONnT dark matter detector

Phys · · 2563 words · By Ingrid Fadelli

Researchers used the XENONnT dark matter detector to test theories of spontaneous quantum collapse, specifically the CSL and Diósi–Penrose models. While no X-ray bursts were detected, the study established the strongest constraints to date on these models and highlighted the synergy between theoretical physics and large-scale experimental detectors.
