Matter Enhanced Neutrino Oscillations with a Realistic Earth Density Profile
Step function approximations of the Earth matter density profile have been used by several authors, see e.g. Refs. [1,2], for the analysis of matter effects in neutrino oscillation experiments. In order to investigate the quality of this approximation, we have developed methods to numerically calculate the transition probability amplitudes in a realistic matter density profile. Calculations wer...
متن کاملMatter-enhanced three-flavor oscillations and the solar neutrino problem.
We present a systematic analysis of the three-flavor Mikheyev-SmirnovWolfenstein (MSW) oscillation solutions to the solar neutrino problem, in the hypothesis that the two independent neutrino square mass differences, δm and m, are well separated: δm ≪ m. At zeroth order in δm/m, the relevant variables for solar neutrinos are δm and two mixing angles, ω and φ. We introduce new graphical represen...
متن کاملNeutrino Oscillations and Dark Matter
The significance of light massive neutrinos as hot dark matter is outlined. The power of neutrino oscillation experiments with respect to detect such neutrinos in the eV-region is discussed. Present hints for neutrino oscillations in solar, atmospheric and LSND data are reviewed as well as future experiments and their potential.
متن کاملA Model for Neutrino Warm Dark Matter and Neutrino Oscillations
The muonand tau-neutrinos with the mass in the keV range, which are allowed in a low reheating temperature cosmology, can compose the warm dark matter of the universe. A model of four light neutrinos including the keV scale νμ and ντ is studied, which combines the seesaw mechanism and the Abelian flavor symmetry. The atmospheric neutrino anomaly is due to the νμ − ντ oscillation. The solar neut...
متن کاملExact Formula of Probability and CP Violation for Neutrino Oscillations in Matter
Within the framework of the standard three neutrino scenario, we derive an exact and simple formula of the oscillation probability P (νe → νμ) in constant matter by using a new method. From this formula, it is found that the matter effects can be separated from the pure CP violation effects. Furthermore, the oscillation probability can be written in the form, P (νe → νμ) = A cos δ + B sin δ + C...
