Abstract
A seismic model for the Sun calculated using the accurate helioseismic data predicts a lower neutrino flux as compared to the standard solar model (SSM). However, there persists a discrepancy between the predicted and measured neutrino fluxes and it seems necessary to invoke neutrino oscillations to explain the measurements. In this work, we have performed a global, unified oscillation analysis of the latest solar neutrino data (including the results of SNO charged current rate) using the seismic model fluxes as theoretical predictions. We determine the best-fit values of the neutrino oscillation parameters and the for both and cases and present the allowed parameter regions in the plane for transition. The results are compared with those obtained using the latest SSM by Bahcall and co-workers.
