Abstract

The Borexino collaboration has recently published the most precise, direct measurement of 7Be solar neutrino rate and the exclusion of a significant day-night asymmetry. These results, combined with the other solar neutrino data, isolate for the first time the Large Mixing Angle solution at Δχ 2 > 190 (2 d.o.f.), without relying on the antineutrino results. We present a phenomenological analysis of neutrino data (the most up-to-date from solar, reactor, atmospheric and accelerator experiments) within the standard scenario of three non-sterile and mixed neutrinos. The aim is to study the implications of Borexino results in neutrino Physics and solar interior astrophysics.
