Solar Neutrinos Astrophysics at LNGS: Borexino and Gallex Experiments

International Symposium on Solar Neutrino Physics at LNGS

The study of solar neutrinos is a fruitful interdisciplinary research topic that had a tremendous impact on both neutrino and astroparticle physics. It led to some of the most significant recent breakthroughs in those fields and greatly improved our understanding of the nuclear reactions that power the Sun and the other stars.

Since its establishment in the 1980s, the Gran Sasso National Laboratory (LNGS) of INFN has been deeply involved in this field, with Gallex (later prolonged as GNO) and Borexino experiments. After over 35 years, this line of research eventually ended with the shutdown of the Borexino detector in October 2021.

Two years after the conclusion of this scientific endeavor, the symposium will present a retrospective that examines themes, results and implications on both neutrino physics and stellar astrophysics of these researches. It will feature contributions from some of the most prominent scientists in the field, who will report on the achievements at LNGS as part of the international effort which began in the 1960s to investigate the properties of neutrinos from the Sun.
