Abstract:
The main results of solar neutrino experiments are presented, ranging from the pioneering Cl – Ar experiment up to the most recent Borexino data. Solar neutrino fluxes and spectra are given for two versions of the standard solar model, and radiochemical and electronic detectors are briefly described. The results of $^7$Be- and pep-neutrino detection by Borexino are presented. The LMA-MSW oscillation solution of the solar neutrino problem is considered.
