摘要：

We perform a global analysis of neutrino oscillation data in the framework of three neutrinos, including the recent improved measurement of the neutral current events at the Sudbury Neutrino Observatory. In addition to all current solar neutrino data, we take into account the reactor neutrino data from KamLAND and CHOOZ, the atmospheric neutrino data from Super-Kamiokande and MACRO, as well as the first spectral data from the K2K long baseline accelerator experiment. The up-to-date best-fit values and allowed ranges of the three-flavor oscillation parameters are determined from these data. Furthermore, we discuss in detail the status of the small parameters alphaequivalent toDeltam(sol)(2)/Deltam(atm)(2) and sin(2) theta(13), which fix the possible strength of CP-violating effects in neutrino oscillations.
