First measurement of low-energy solar neutrinos scattering off electrons

Researchers in the XENON Collaboration have successfully observed low-energy solar neutrinos scattering off electrons using the XENONnT detector in Italy. This achievement marks the lowest energy threshold for direct neutrino detection ever recorded.

Credit: Henning Schulze Eissing Every second, tens of billions of neutrinos produced by nuclear fusion in the sun pass through every square centimeter of Earth—and through our bodies—almost without interacting. Although they are among the most abundant particles emitted by the sun, their extremely weak interactions make detecting these elusive particles one of the greatest experimental challenges in particle physics. A number of specialized neutrino detectors are in operation around the world, exploiting the unique properties of neutrinos to investigate astrophysical phenomena.
