Mikheyev-Smirnov-Wolfenstein Effect for Linear Electron Density
When the electron density is a linear function of distance, it is known that the MSW equations for two neutrino species can be solved in terms of known functions. It is shown here that more generally, for any number of neutrino species, these MSW equations can be solved exactly in terms of single integrals. While these integrals cannot be expressed in terms of known functions, some of their sim...
متن کاملNo Mikheyev-Smirnov-Wolfenstein Effect in Maximal Mixing
We investigate the possible influence of the MSW effect on the expectations for the solar neutrino experiments in the maximal mixing scenario suggested by the atmospheric neutrino data. A direct numerical calculation of matter induced effects in the Sun shows that the naive vacuum predictions are left completely undisturbed in the particular case of maximal mixing, so that the MSW effect turns ...
متن کاملSearching for the Msw Enhancement
We point out that the length scale associated with the MSW effect is the radius of the Earth. Therefore to verify matter enhancement of neutrino oscillations, it will be necessary to study neutrinos passing through the Earth. For the parameters of MSW solutions to the solar neutrino problem, the only detectable effects occur in a narrow band of energies from 5 to 10 MeV. We propose that serious...
متن کاملOn the Paschos–Wolfenstein Relationship for Nuclei
Nuclear effects and QCD perturbative corrections to the Paschos–Wolfenstein relationship are discussed. We argue that perturbative corrections largely cancel out in this relationship for total cross sections while the neutron excess correction in heavy nuclei is enhanced by Fermi motion and nuclear binding effects. These observations are discussed in the context of NuTeV measurement of the Wein...
متن کاملWolfenstein parametrization reexamined.
The Wolfenstein parametrization of the 3 × 3 Kobayashi-Maskawa (KM) matrix V is modified by keeping its unitarity up to the accuracy of O(λ). This modification can self-consistently lead to the off-diagonal asymmetry of V : |Vij| 2 − |Vji| 2 = Z ∑ k ǫijk with Z ≈ Aλ(1 − 2ρ), which is comparable in magnitude with the Jarlskog parameter of CP violation J ≈ Aλη . We constrain the ranges of J and Z...
