摘要：

We consider the impact of the recent KamLAND data on neutrino oscillations, the first terrestrial neutrino experiment that can probe the solar neutrino anomaly. By combining the first 145.1 days of KamLAND data with the full sample of the latest solar neutrino data we find an enhanced rejection against non-large-mixing-angle (LMA) oscillations, allowed only at more than 4 sigma with respect to the LMA solution. Furthermore, the new data have a strong impact in narrowing down the allowed range of Deltam(2) inside the LMA region. In contrast, our global analysis indicates that the new data have little impact on the location of the best fit point. In particular, the solar neutrino mixing remains significantly nonmaximal (3 sigma).
