Abstract: Measuring all neutrino components is the most direct way to test thestandard solar model (SSM). Despite the great results obtained so far,important questions such as the solar metallicity remain open. A precisemeasurement of the solar pp chain and the CNO cycle would settle thiscontroversy between high (HZ) and low (LZ) metallicity compositions ofthe Sun. Solar neutrinos allow the determination of oscillation parameters,in particular the θ 12 mixing angle and, to a lesser degree the ∆m 212 masssplitting. Furthermore the measurement of the electron neutrino survivalprobability Pee as a function of neutrino energy allows one to directlyprobe the MSW-LMA mechanism of neutrino oscillations In this work Iwill report the first simultaneous precision spectroscopic measurement ofthe complete pp-chain and its implications for both solar and neutrinophysics with the Borexino detector.
