We report the measurement of {nu}-e elastic scattering from {sup 8}B solar neutrinos with 3 MeV energy threshold by the Borexino detector in Gran Sasso (Italy). The rate of solar neutrino-induced electron scattering events above this energy in Borexino is 0.22{+-}0.04(stat){+-}0.01(syst) cpd/100 t, which corresponds to {Phi}{sub {sup 8}B}{sup ES}=2.4{+-}0.4{+-}0.1x10{sup 6} cm{sup -2} s{sup -1}, in good agreement with measurements from SNO and SuperKamiokaNDE. Assuming the {sup 8}B neutrino… 
Improved measurement of B8 solar neutrinos with 1.5  kt·y of Borexino exposure
We report on an improved measurement of the $^8$B solar neutrino interaction rate with the Borexino experiment at the Laboratori Nazionali del Gran Sasso. Neutrinos are detected via their elastic

New limits on heavy sterile neutrino mixing in 8B decay obtained with the Borexino detector
If heavy neutrinos with mass $m_{\nu_{H}}\geq$2$ m_e $ are produced in the Sun via the decay ${^8\rm{B}} \rightarrow {^8\rm{Be}} + e^+ + \nu_H$ in a side branch of pp-chain, they would undergo the
Measurement of the B8 solar neutrino flux in SNO+ with very low backgrounds
A measurement of the 8B solar neutrino flux has been made using a 69.2 kt-day dataset acquired with the SNO+ detector during its water commissioning phase. At energies above 6 MeV the dataset is an
