Relic neutrino decoupling including flavour oscillations
In the early universe, neutrinos are slightly coupled when electron-positron pairs annihilate transferring their entropy to photons. This process originates non-thermal distortions on the neutrino spectra which depend on neutrino flavour, larger for νe than for νμ or ντ . We study the effect of three-neutrino flavour oscillations on the process of neutrino decoupling by solving the momentum-dep...
متن کاملNeutrino flavour relaxation or neutrino oscillations ?
We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino flavour relaxation model can be done in fu...
متن کاملSolar-neutrino oscillations and third-flavour admixture
With one ∆m of the appropriate order of magnitude to solve the atmospheric neutrino problem, we study the resulting three-generation vacuumoscillation fit to the solar neutrino flux. An explanation of the atmospheric neutrino composition in terms of pure νμ → ντ oscillations is easily compatible with the well-known two-flavour oscillation solution for solar neutrinos. The allowed parameter regi...
متن کاملDecoupling of solar and atmospheric neutrino oscillations
The scheme of mixing of three neutrinos with a mass hierarchy is considered for the explanation of the solar and atmospheric neutrino problems through neutrino oscillations. It is shown that the recent results of the CHOOZ experiment imply that the element Ue3 of the neutrino mixing matrix is small, that the oscillations of solar neutrinos are described by the two-generation formalism and that ...
متن کاملEffects of non-standard neutrino-electron interactions on relic neutrino decoupling
We consider the decoupling of neutrinos in the early Universe in presence of nonstandard neutral current neutrino-electron interactions (NSI). We first discuss a semi-analytical approach to solve the relevant kinetic equations and then present the results of fully numerical and momentum-dependent calculations, including flavor neutrino oscillations. We present our results in terms of both the e...
