چکیده

Both gravitational and mass induced neutrino oscillation mechanisms provide possible resolutions to the Solar Neutrino Problem. The distinguishing feature between the two mechanisms is their dependence on the neutrino energy. We investigate the implications of this by computing the B neutrino spectrum as determined from each mechanism using a realistic three–flavor evolution model. We find that in the limit of small θ13 mixing angle, the differences are significant enough to observe in future solar neutrino experiments. [email protected] [email protected]

Three-flavor gravitationally induced neutrino oscillations and the solar neutrino problem.

Some implications of the proposal that flavor nondiagonal couplings of neutrinos to gravity might resolve the solar neutrino problem are considered in the context of three neutrino flavors. The two– flavor model is discussed as a limiting case of the full three-generation mechanism, and the behavior of the νe survival probability for various values of the three–flavor parameters is studied. Ove...

Pulsar Velocity with Three - Neutrino Oscillations in Non - adiabatic Processes

We have studied the position dependence of neutrino energy on the Kusenko-Segrè mechanism as an explanation of the proper motion of pulsars. The mechanism is also examined in three-generation mixing of neutrinos and in a non-adiabatic case. The position dependence of neutrino energy requires the higher value of magnetic field such as B ∼ 3 × 10 15 Gauss in order to explain the observed proper m...

Solar neutrino problem and gravitationally induced long-wavelength neutrino oscillation

We have reexamined the possibility of explaining the solar neutrino data through long-wavelength neutrino oscillations induced by a tiny breakdown of the weak equivalence principle of general relativity. We have found that such gravitationally induced oscillations can provide a viable solution to the solar neutrino problem.

Solar Neutrino Oscillation Diagnostics at Superkamiokande and Sno

Results for solar neutrino detection from the SuperKamiokande collaboration have been presented recently while those from the Sudbury Neutrino Observatory are expected in the near future. These experiments are sensitive to the B neutrinos from the sun, the shape of whose spectrum is well-known but the normalisation is less certain. We propose several variables, insensitive to the absolute flux ...

Gravitationally Induced Quantum Mechanical Phases and Neutrino Oscillations in Astrophysical Environments

We report a new effect of gravitationally induced quantum mechanical phases in neutrino oscillations. In the neighborhood of a neutron star, gravitationally induced quantum mechanical phases are roughly 15% of their kinematical counterparts. When this information is coupled with the mass square differences implied by the existing neutrino–oscillation data we find that the ∗This work was done, i...
