Abstract

The rate of neutrino-electron elastic scattering interactions from 862 keV Be7 solar neutrinos in Borexino is determined to be 46.0±1.5(stat)-1.6+1. 5(syst)counts/(day•100ton). This corresponds to a ν_e- equivalent Be7 solar neutrino flux of (3.10±0.15)×109cm ^-2s^-1 and, under the assumption of ν_e transition to other active neutrino flavours, yields an electron neutrino survival probability of 0.51±0.07 at 862 keV. The no flavor change hypothesis is ruled out at 5.0σ. A global solar neutrino analysis with free fluxes determines Φ_pp=6.06-0.06+0.02×1010cm ^-2s^-1 and Φ_CNO<1.3×109cm ^-2s^-1 (95% C.L.). These results significantly improve the precision with which the Mikheyev-Smirnov-Wolfenstein large mixing angle neutrino oscillation model is experimentally tested at low energy.
