Solar Neutrino Oscillation Parameters after SNO Phase-Ⅲ and SAGE Part-Ⅲ

We analyse the recently published results from solar neutrino experiments SNO Phase-Ⅲ and SAGE Part-Ⅲ and show their constraints on solar neutrino oscillation parameters, especially for the mixing angle θ12. Through a global analysis using all existing data from SK, SNO, Ga＆Cl radiochemieal experiments and long base fine reactor experiment KamLAND, we obtain the parameters △m12^2= 7.684 -0.208^＋0.212×10^-5 eV^2, tan^2 θ12=0.440-0.057^＋0.059. also find that the discrepancy between the KamLAND and solar neutrino results can be reduced by choosing a small non-zero value for the mixing angle θ13.
