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 favour of the LMA solution comes
from the KamLAND reactor neutrino data. The KamLAND 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 Δm
2 region (low-LMA) and high Δm
2 region (high-LMA). We demonstrate through a projected analysis that with an exposure of 3 kton-year (kTy) KamLAND can remove
this ambiguity. |
