Borexino: Latest Results and Future Opportunities

Abstract

The Borexino experiment, located at the Laboratori Nazionali del Gran Sasso in Italy, is the liquid-scintillator experiment that has tackled an extensive physics program for more than ten years. Its distinctive technical feature, the ultra-low radioactive background of the inner scintillating core, has exceeded all expectations and became the basis of the outstanding achievements obtained so far. The Borexino collaboration has recently published the first comprehensive measurement of solar neutrinos produced along the pp-chain, a sequence of nu- clear reactions responsible for about 99 percent of solar energy. We present the measurements of pp, 7Be, pep, and 8B solar neutrino interaction rates, as well as the limits on hep and CNO-cycle contributions. Besides these solar neutrino results and their implications we explore the possible strategies on CNO-neutrino measurements
