Solar Neutrino Oscillation Phenomenology

Abstract

This article summarises the status of the solar neutrino oscillation phenomenology at the end of 2002 in the light of the SNO and KamLAND results. We first present the allowed areas obtained from global solar analysis and demonstrate the preference of the solar data towards the Large-Mixing-Angle (LMA) MSW solution. A clear confirmation in favor of the LMA solution comes from the \kl reactor neutrino data. The \kl spectral data in conjunction with the global solar data further narrows down the allowed LMA region and splits it into two allowed zones -- a low $\Delta m^2$ region (low-LMA) and high $\Delta m^2$ region (high-LMA). We demonstrate through a projected analysis that with an exposure of 3 kton-year (kTy) \kl can remove this ambiguity.
