Borexino is a real-time experiment for low energy neutrino spectroscopy, operating at the Laboratori Nazionali del Gran Sasso (Italy). Borexino is the first experiment to report a real-time observation of low energy solar neutrinos below 4.5 MeV, which were not accessible so far with the state-of the art detector technologies because of natural radioactivity. The results reported in this work present the real-time measurement of the low energy (0.862 MeV) 7Be solar neutrinos with the Borexino detector from an analysis of 192 live days in the period from May 16, 2007 to April 12, 2008, totaling a 41.3 ton·yr fiducial exposure to solar neutrinos. Additionally we show data on solar 8B neutrinos with an energy threshold of 2.8 MeV.

Abstract
Borexino is a real-time experiment for low energy neutrino spectroscopy, operating at the Laboratori Nazionali del Gran Sasso (Italy). Borexino is the first experiment to report a real-time observation of low energy solar neutrinos below 4.5 MeV, which were not accessible so far with the state-of the art detector technologies because of natural radioactivity. The results reported in this work present the real-time measurement of the low energy (0.862 MeV) 7Be solar neutrinos with the Borexino detector from an analysis of 192 live days in the period from May 16, 2007 to April 12, 2008, totaling a 41.3 ton·yr fiducial exposure to solar neutrinos. Additionally we show data on solar 8B neutrinos with an energy threshold of 2.8 MeV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
