摘要

Until 2010 we had three unknown parameters of neutrino oscillation-the third mixing angle theta(13), the sign of the larger mass difference Delta m(31)(2) and the CP violating phase delta. Thanks to a number of consistent experimental results since then, culminating in the recent Daya Bay reactor neutrino data, we now have a definitive determination of theta(13). Moreover its measured value, sin(2)2 theta(13) approximate to 0.1, is close to its earlier upper limit. This has promising implications for the determination of the two remaining unknown parameters from the present and proposed accelerator neutrino experiments in the foreseeable future. This article presents a pedagogical review of these profound developments for the wider community of young physicists including university students.
