Introduction to Sterile Neutrinos
Model-building issues raised by the prospect of light sterile neutrinos are discussed in a pedagogical way. I first review the näıve proposal that sterile neutrinos be identified with “right handed neutrinos”. A critical discussion of the simple expedient of adding three gauge singlet fermions to the usual minimal standard model matter content is followed by an examination of right handed neutr...
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 کاملHow to Find Sterile Neutrinos?
We describe an extention of the Standard Model (the νMSM) by three light singlet Majorana fermions – sterile neutrinos, which allows to address simultaneously the problem of neutrino oscillations and the problems of dark matter and baryon asymmetry of the Universe. We discuss the ways these new particles can be searched for in astrophysical, laboratory, and accelerator experiments.
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...
