LMA MSW solution of the solar neutrino problem and first KamLAND results
The first KamLAND results are in a very good agreement with the predictions made on the basis of the solar neutrino data and the LMA realization of the MSW mechanism. We perform a combined analysis of the KamLAND (rate, spectrum) and the solar neutrino data with a free boron neutrino flux fB. The best fit values of neutrino parameters are ∆m2 = 7.3 · 10−5 eV2, tan2 θ = 0.41 and fB = 1.05 with t...
متن کاملThe Solar Neutrino Problem after the first results from Kamland
The first results from the KamLAND experiment have provided confirmational evidence for the Large Mixing Angle (LMA) MSW solution to the solar neutrino problem. We do a global analysis of solar and the recently announced KamLAND data (both rate and spectrum) and investigate its effect on the allowed region in the ∆m − tan θ plane. The best-fit from a combined analysis which uses the KamLAND rat...
متن کاملThe Lma Msw Solution of the Solar Neutrino Problem, Inverted Neutrino Mass Hierarchy and Reactor Neutrino Experiments
In the context of three-neutrino oscillations, we study the possibility of using antineutrinos from nuclear reactors to explore the 10−4 eV2 < ∆m⊙ ∼< 8 × 10 −4 eV2 region of the LMA MSW solution of the solar neutrino problem. The KamLAND experiment is not expected to determine ∆m⊙ if the latter happens to lie in the indicated region. By analysing both the total event rate suppression and the en...
متن کاملImplications of New Gallex Results for the Msw Solution of the Solar Neutrino Problem
We compare the implications for Be and pp neutrinos of the two MSW fits to the new GALLEX solar neutrino measurements . Small mixing angle solutions tend to suppress the former as electron-neutrinos, but not the latter, and large angle solutions tend to reduce both by about a factor of 2. The consequences for BOREXINO and similar solar neutrino–electron scattering experiments are discussed. The...
متن کاملSolving Solar Neutrino Puzzle via LMA MSW Conversion
We analyze the existed solar neutrino experiment data and show the allowed regions. The result from SNO’s salt phase itself restricts quite a lot the allowed region’s area. Reactor neutrinos play an important role in determining oscillation parameters. KamLAND gives decisive conclusion on the solution to the solar neutrino puzzle, in particular, the spectral distortion in the 766.3 Ty KamLAND d...
