Constraints on the Neutrino Parameters from the `Rise-up' in the Boron Neutrino Spectrum at Low Energies
The rise-up in boron neutrino spectrum at low energies has been studied
within the framework of `pure LMA' scenario. Indirect bounds on the spectral
`upturn' have been obtained from the available solar neutrino data. These
bounds have been used to demonstrate the efficacy of the precision measurements
of the `upturn' for further constraining the neutrino parameter space allowed
by SNO salt phase data. The sterile neutrino flux has been constrained in the
light of the recent 766.3 Ty KamLAND spectral data.Comment: Latex 10pages including 3 postscript figure
