First measurement of low-energy solar neutrinos scattering off electrons
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 …

Science and Haitek: The scientific collation of XENONNT, in which scientists from the Weitzman Institute actively participate, has recorded solar neutrino with record low energy, and it has not been possible to see these particles before.
The XENON Collaboration Sees A 5σ Signal For Low-energy Solar Neutrinos
The XENON Collaboration announced the first observation of low-energy solar neutrinos scattering off electrons in the XENONnT detector, extending direct neutrino observations down to about 17 keV. The measurement detects pp neutrinos, produced in proton–proton fusion reactions, and represents a 5σ signal—the statistical significance conventionally used to claim a discovery.
Rome, 31 Aug. (askanews) - Today, during a seminar at the National Laboratories of the Gran Sasso dell'Infn (LNGS), the collaboration XENON announced the first observation of the elastic scattering of low-energy solar neutrinos on electrons in the XENONNT detector. The result, submitted to the journal Physical Review X and already available on the website of [...]
