Abstract
Borexino, in data taking since May 2007, is the only experiment capable to perform the measurement of low-energy solar-ν. Borexino has performed the first direct measurement of the 7Be solar-ν rate with accuracy better than 5%. The absence of day-night asymmetry of the 7Be solar-ν rate was measured with a total uncertainty of 1%. Borexino results alone reject the Low Δm2 (LOW) region of solar-ν oscillation parameters at more than 8.5 σ CL. Combined with the other solar-ν data, Borexino measurements isolate the Large Mixing Angle (LMA)- Mikheyev Smirnov Wolfenstein (MSW) solution of neutrino oscillations without assuming CPT invariance in the neutrino sector.
