Neutrino mass parameters from Kamland, SNO, and other solar evidence

An updated analysis of all available neutrino oscillation evidence in reactor (Kamland, first 145 days of data) and solar experiments (SK day and night spectra, global rates from Homestake, SAGE, and GALLEX) including the SNOCC and NC data is presented. In the framework of two active neutrino oscillations we determine the allowed regions in neutrino parameter space; we obtain, from the Kamland spectral shape and global signal, the following antineutrino best solution parameters:

is that the large mixing angle (LMA) region remains the only one that is still favored. Combining Kamland and solar data and assuming CPT invariance, i.e., the same mass matrix for neutrinos and antineutrinos, we obtain the following antineutrino best solution parameters (LMAI solution):
