Can three-flavor oscillations solve the solar neutrino problem?
arXiv:hep-ph/0102063 · doi:10.1103/PhysRevD.64.013009
Abstract
The most promising solution to the solar neutrino problem are neutrino oscillations, which usually are analyzed within the reduced 2-flavor scheme, because the solutions found therein reasonably well reproduce the recent data of Super-Kamiokande about the recoil-electron energy spectrum, zenith-angle and seasonal variations, and the event rate data of all the neutrino detectors. In this work, however, a survey of the complete parameter space of 3-flavor oscillations is performed. Basically eight new additional solutions could be identified, where the best one with Δm(12)^2=2.7x10^(-10) eV^2, Δm(13)^2=1.0x10^(-5) eV^2, Θ(12)=23, and Θ(13)=1.3 (denoted SVO) is slightly more probable than any 2-flavor solution. However, including the results of the atmospheric neutrino problem excludes all 3-flavour solutions apart from the SLMA-solution (Δm(12)^2=7.9x10^(-6) eV^2, Δm(13)^2=2.5x10^(-4) eV^2, Θ(12)=1.4, and Θ(13)=20). Besides, the ability of SNO and Borexino to discriminate the various 2- and 3-flavor solutions is investigated. Only with very good statistics in these experiments the correct solution to the solar neutrino problem can be identified unambiguously.
