Search for New Physics in Electronic Recoil Data from XENONnT
We report on a blind analysis of low-energy electronic-recoil data from the first science run of the XENONnT dark matter experiment. Novel subsystems and the increased 5.9 tonne liquid xenon target reduced the background in the (1, 30) keV search region to $(16.1 \pm 1.3)$ events/(tonne$\times$year$\times$keV), the lowest ever achieved …
