Più di 35 anni a caccia dei neutrini hanno permesso di svelare cosa succede nel cuore del Sole: si devono a Gallex e Borexino l’osservazione e la prova dei processi che alimentano la nostra stella (ANSA).
The symposium, which will be held on Sept. 12, 2023 at Accademia dei Lincei in Rome, will present a retrospective of themes, results and implications of researches on Solar Neutrino at LNGS, featuring some of the most prominent scientists in the field.

Latest Borexino CNO pre-print results(1) featured on Science News: “Neutrinos hint the sun has more carbon and nitrogen than previously thought Figuring out our star’s makeup is crucial for understanding the entire universe” By Ken Croswell JUNE 16, 2022 AT
Physicsworld magazine dedicated an article to our recently published papers about directional measurement of Sub-MeV solar neutrinos with Borexino: Until now, physicists measuring the properties of solar neutrinos have had to make a compromise – either measure the particles’ energy with
Thanks to its extraordinary radiopurity, Borexino observed the two main fusion reactions in stars and will soon weigh in on a controversy relating to the birth of the Sun that challenges the SSM (G.Bellini & A.Ianni on CERN Courier)

Sensitivity to neutrinos from the solar CNO cycle in Borexino Eur. Phys. J. C 80, 1091 (2020) [doi:10.1140/epjc/s10052-020-08534-2] published 26 November 2020 (cover story) This paper have been been highlighted on EPJ C Highlight, Springer Research News and Europhysics News
For most of their existence, stars are powered by fusion of hydrogen into helium via two processes that are well understood theoretically: the proton–proton chain, dominant in relatively small stars like our Sun, and the Carbon–Nitrogen–Oxygen cycle, which is prevalent in bigger, more massive stars. Borexino got the first experimental evidence of neutrinos emitted by the CNO cycle in the Sun core.
After recalling the main features of the detector, the impressive solar data gathered so far by the experiment will be summarized.
CERN Courier : Neutrinos confirm rare solar fusion process
Detection of particles produced by the Sun’s core supports long-held theory about how our star is powered. By catching neutrinos emanating from the Sun’s core, physicists have filled in the last missing detail of how nuclear fusion powers the stars.
