Comment on Radiative Neutrino Mass Matrix with a Sterile Neutrino
New era of physics beyond the standard quark-lepton physics has been opened by the SuperKamiokande collaboration who has provided the convincing evidence on atmospheric neutrino oscillations. [1] There have also been other observed anomalous phenomena suggesting that neutrinos are oscillating, which are often referred to the solar neutrino deficit [2] and to the LSND signal [3]. Such neutrino o...
متن کاملLight Unstable Sterile Neutrino
The three massless active (doublet) neutrinos may mix with two heavy and one light sterile (singlet) neutrinos so that the induced masses and mixings among the former are able to explain the present data on atmospheric and solar neutrino oscillations. If the LSND result is also to be explained, one active neutrino mass eigenstate must mix with the light sterile neutrino. A specific model is pro...
متن کاملSterile Neutrino as a Bulk Neutrino
If light sterile neutrinos are needed to understand the neutrino puzzles, as is currently indicated, a major theoretical challenge is to understand why its mass is so small. It is a more serious problem than understanding the small mass of the familiar neutrinos. We discuss a new way to solve this problem by identifying the sterile neutrino as gauge neutral fermion propagating in the bulk of a ...
متن کاملSterile neutrino states
Neutrino masses are likely to be a manifestation of the right-handed, or sterile neutrinos. The number of sterile neutrinos and the scales of their Majorana masses are unknown. We explore theoretical arguments in favor of the high and low scale seesaw mechanisms, review the existing experimental results, and discuss the astrophysical hints regarding sterile neutrinos. 1. Sterile neutrinos in pa...
متن کاملGravitino as a Sterile Neutrino
A scheme is described in which the light gravitino in low energy SUSY breaking models mixes with neutrinos. The mixing between gravitino and neutrinos arises through the standard model symmetry breaking and an R-parity and lepton number violating bilinear term in the superpotential. It is shown that mixings compatible with the neutrino experiments can be obtained within the cosmological bound o...
