LNGS: A. VISHNEVA - SIMULTANEOUS SPECTROSCOPY OF PP, 7BE AND PEP SOLAR NEUTRINOS IN THE PHASE II OF BOREXINO EXPERIMENT 
 ELENCO COMPLETO 

DATA: 20-11-2017

LABORATORI NAZIONALI DEL GRAN SASSO
The recent analysis of the Borexino Phase II data gives new results for fluxes of solar neutrinos from pp, 7Be and pep reactions with a significantly better precision. Namely, pp and 7Be neutrino fluxes are measured with 10% and 3% precision, respectively, while neutrinos from the pep reaction are observed with the significance exceeding 5 standard deviations for the first time. Improvements in analysis techniques made it possible to perform a simultaneous spectral fit including all three solar neutrino spectral components. In addition, a limit on the CNO neutrino flux has been obtained and a possibility of solving the solar metallicity issue is studied. --- A. Vishneva JINR Dubna Russia
