Theoretical Implications of the Combined Solar Neutrino Observations

Abstract

Constraints on the core temperature of the Sun and on neutrino-oscillation parameters are obtained by comparing the combined Homestake, Kamiokande, SAGE and GALLEX solar neutrino data with Standard Solar Models (SSM) and with non-standard solar models parameterized by a phenomenological central temperature ($T_c$). If the Sun is 2\% cooler or 3\% warmer than predicted by SSMs, the MSW parameters we determine are consistent with different grand unified theories.
