Sterile Neutrinos in astrophysical and cosmological sauce
The study of sterile neutrinos has recently acquired a different flavor: being now excluded as the dominant solution for the solar or atmospheric conversions, sterile neutrinos, still attractive for many other reasons, have thus become even more elusive. The present relevant questions are: which subdominant role can they have? Where (and how) can they show up? Cosmology and supernovæ turn out t...

متن کاملSterile neutrinos
Neutrino masses are usually described by adding to the Standard Model some SU(2)singlet fermions that have the Yukawa couplings, as well as some Majorana mass terms. The number of such fields and the scales of their Majorana masses are not known. Several independent observations point to the possibility that some of these singlets may have masses well below the electroweak scale. A sterile neut...
متن کاملSterile neutrinos and RK
We consider an enhancement in the violation of lepton flavour universality in light meson decays arising from modified Wlν couplings in the standard model minimally extended by sterile neutrinos. Due to the presence of additional mixings between the active neutrinos and the new sterile states, the deviation from unitarity of the leptonic mixing matrix intervening in charged currents might lead ...
متن کاملMiniBooNE and Sterile Neutrinos
Sterile neutrinos may be an important extension to the standard model, and could both hold the key to understanding neutrino mass and mixing as well as play an important role in leptogenesis. In many models, the sterile neutrinos could be light and accessible to current and near term experiments. The MiniBooNE experiment is set up to explore these possibilities in the ∆m region from 0.3 to a fe...
