First measurement of a nuclear recoil signal from solar neutrinos with XENONnT
Alongside hypothetical dark matter particles, neutrinos from the sun have long been predicted to be observable in detectors built to search for dark matter nuclear recoil signals. The XENON collaboration has now succeeded in proving this. The Institute of Nuclear Physics at the University of Münster, headed by Prof. Dr. Christian Weinheimer, was also involved. Solar neutrinos are the lightest known elementary particles; they are created in nuclear processes in the sun's interior.
