摘要：Status of the solar neutrino studies after KamLAND and the SNO salt phase
experiment is summarized. The present data determine quantitatively the physical picture
of the solar neutrino conversion. The next step in the eld will be related to further
checks of the LMA MSW solution, precision measurements of the oscillation parameters,
searches for sub-leading e
ects and studies of solar neutrino fluxes. The predictions
for the forthcoming measurements are given which include the spectral distortion and
CC/NC ratio at SNO, the Day-Night asymmetry, the KamLAND spectrum and rate.
The Homestake result is about 2 lower than the Ar-production rate, QAr, predicted
by the LMA MSW solution. Also there is no apparent \upturn" of the energy spectrum
(R Nobs=NSSM) at low energies in SNO and Super-Kamiokande. Both these facts
can be explained if a light sterile neutrino exists which mixes very weakly with active
neutrinos. Future studies of the solar neutrinos by SNO, SK, BOREXINO and KamLAND
as well as by the new low energy experiments will allow us to check this possibility. In
connection to future precision measurements of the solar neutrino fluxes e
ects of the
non-zero 13-mixing are considered.
