Active and sterile neutrino oscillations inside the Sun in a phenomenological (3+1+2)-model | V. V. Khruschov

22 Oct 2013 | Abstract: | A generalized model with three active and three sterile neutrinos is
considered on the basis of the experimental data, which allow existence of
anomalies beyond the minimally extended Standard Model with three active
neutrinos with different masses. One of the sterile neutrinos is assumed to be
comparatively heavy versus two others [$(3+1+2)$-model]. The basic
characteristics used for the description of oscillations of both active and
sterile massive neutrinos, as well as estimations of the neutrino masses and
unknown parameters of mixing of active and sterile neutrinos are given. In the
approximation of CP-conservation, the solar neutrino oscillation
characteristics together with the sterile neutrino contributions are evaluated
taking into account the neutrino interaction with the matter inside the Sun.
The considered model and the results obtained can further be used for the
interpretation and prediction of the results of the oscillation neutrino
experiments in astrophysical and terrestrial environments, and in particular,
for determination of flavour flows of the neutrinos from Supernovae. | Source: | arXiv, 1310.5817 | Services: | Forum | Review | PDF | Favorites |
