How Well Do We (and Will We) Know Solar Neutrino Fluxes and Oscillation Parameters?

Abstract

Assuming neutrino oscillations occur, the pp electron neutrino flux is uncertain by at least a factor of two, the ${}^8\mathrm{B}$ flux by a factor of five, and the ${}^7\mathrm{Be}$ flux by a factor of forty-five. Calculations of the expected results of future solar neutrino experiments (SuperKamiokande, SNO, BOREXINO, ICARUS, HELLAZ, and HERON) are used to illustrate the extent to which these experiments will restrict the range of the allowed neutrino mixing parameters. We present an improved formulation of the ``luminosity constraint'' and show that at 95\% confidence limit this constraint establishes the best available limits on the rate of creation of pp neutrinos in the solar interior and provides the best upper limit to the ${}^7\mathrm{Be}$ neutrino flux.
