Aug 2007 – first results on 7Be neutrino appeared

8. Borexino current results/future Borexino operates at purity levels never achieved before, it demonstrated the feasibility of the neutrino flux measurement in sub-MeV region, under the natural radioactivity threshold (4.2 MeV); Solar 7 Be- flux has been measured with 10% accuracy; a first measurement of 8 B- in LS with threshold below 5 MeV (2.8 MeV); Borexino results are compatible with MSW/LMA; strong limit on neutrino effective magnetic moment is obtained; extremely high sensitivity to electron antineutrino has been experimentally confirmed, waiting for more statistics. Further calibration and reduction of the error on the 7 Be flux down to 5% (further improvements if constraining 85 Kr, in this case also the limits on the effective magnetic moment will be improved); Seasonal variations of the neutrino fluxes (detector stability, more statistics); other time variations More precise measurement of the oscillation probability in the transition region (either due to the higher statistics or due to increase of the FV); The CNO and pep-neutrino fluxes measurement (requires cosmogenic 11 C tagging); The feasibility of the pp-neutrino flux measurement is under study (better understanding of the detector at low energies and the precise spectral shape of 14 C is needed); Antineutrino studies: geo, reactor, supernova.
