摘要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 radiochemical experiments and long base line reactor experiment KamLAND, we obtain the parameters Δm212=7.684+0.212-0.208×10-5,eV2, tan2θ12=0.440+0.059-0.057. We 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.
