Abstract:
Measuring all neutrino components is the most direct way to test the standard solar model (SSM). Despite the great results obtained so far, important questions such as the solar metallicity remain open. A precise measurement of the solar pp chain and the CNO cycle would settle this controversy between high (HZ) and low (LZ) metallicity compositions of the Sun. Solar neutrinos allow the determination of oscillation parameters, in particular the θ12 mixing angle and, to a lesser degree the Δm212 mass splitting. Furthermore the measurement of the electron neutrino survival probability Pee as a function of neutrino energy allows one to directly probe the MSW-LMA mechanism of neutrino oscillations In this work I will report the first simultaneous precision spectroscopic measurement of the complete pp-chain and its implications for both solar and neutrino physics with the Borexino detector.
