Status of the BOREXINO Solar Neutrino Experiment
Aim of BOREXINO is to measure in real time low energetic solar neutrinos via neutrino electron scattering. Special interest in BOREXINO is the measurement of the counting rate of the 861 keV 7 Be solar neutrinos in order to separate between scenarios beyond the standard model which are favored by the results of running solar neutrino experiments. The solar neutrino puzzle originates from the di...

متن کاملSolar neutrino experiments and Borexino perspectives
We present an updated analysis of all the data available about solar neutrinos, including the charged current SNO results. The best fit of the data is obtained in the Large Mixing Angle region, but different solutions are still possible. We also study the perspectives of Borexino and conclude that this experiment, with a parallel analysis of total rate and day-night asymmetry, should be able to...
متن کاملConstraining neutrino magnetic moment with solar and reactor neutrino data
We use solar neutrino data to derive stringent bounds on Majorana neutrino transition moments (TMs). Such moments, if present, would contribute to the neutrino– electron scattering cross section and hence alter the signal observed in Super-Kamiokande. Using the latest solar neutrino data, combined with the results of the reactor experiment KamLAND, we perform a simultaneous fit of the oscillati...
متن کاملSolar Neutrino Flux
We have measured the Coulomb dissociation of 8B into 7Be and proton at 254 MeV/nucleon using a large-acceptance focusing spectrometer. The astrophysical S17 factor for the 7Be(p,γ)8B reaction at Ec.m. = 0.25−2.78 MeV is deduced yielding S17(0) = 20.6± 1.2 (exp.) ± 1.0 (theo.) eV-b. This result agrees with the presently adopted zero-energy S17 factor obtained in directreaction measurements and w...
