(A) Neutrino fluxes and event ratios

$\phi _{{{\overline{\mathit \nu}}_{{{e}}}}}$ (${}^{8}\mathrm {B}$) INSPIRE search

Searches are made for electron antineutrino flux from the Sun. Flux limits listed here are derived relative to the BS05(OP) Standard Solar Model ${}^{8}\mathrm {B}$ solar neutrino flux ($5.69 \times 10^{6}$ cm${}^{-2}~$s${}^{-1}$), with an assumption that solar ${{\overline{\mathit \nu}}_{{{e}}}}$s follow an unoscillated ${}^{8}\mathrm {B}$ neutrino spectrum.

¹ AGOSTINI 2021 derived this result relative to the Standard Solar Model ${}^{8}\mathrm {B}$ solar neutrino flux, under an assumption of high solar metallicity, of 5.46 ($1$ $\pm0.12){\times }10^{6}$ cm${}^{-2}$s${}^{-1}$ (see VINYOLES 2017).

² Superseded by AGOSTINI 2021.

³ BALATA 2006 obtained this result from the search for ${{\overline{\mathit \nu}}_{{{e}}}}$ interactions with Counting Test Facility (the prototype of the Borexino detector).
