Solar neutrino results from Borexino and main future perspectives
M. Pallavicini (for the Borexino Collaboration)
TL;DR
Borexino has successfully measured the $^7$Be solar neutrino flux for the first time and also measured the $^8$B neutrino flux, with background levels meeting or exceeding design goals, opening new research opportunities.
Contribution
First measurement of $^7$Be solar neutrino flux and detailed $^8$B flux measurement with low energy threshold in Borexino.
Findings
Successful measurement of $^7$Be neutrino flux
Measurement of $^8$B neutrino flux at 2.8 MeV threshold
Background levels meet or exceed design expectations
Abstract
Borexino is a solar neutrino experiment running at the Laboratori Nazionali del Gran Sasso, Italy. The radioactive background levels in the liquid scintillator target meet or even exceed design goals, opening unanticipated opportunities. The main results, so far, are the measurement of the Be solar neutrino flux (the first ever done) and the measurement of the B neutrino flux performed with electron energy threshold of 2.8 MeV. The short and medium term perspectives are summarized in the conclusions.
