Light 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 کاملConnecting Bimaximal Neutrino Mixing to a Light Sterile Neutrino
It is shown that if small neutrino masses owe their origin to the conventional seesaw mechanism and the MNS mixing matrix is in the exact bimaximal form, then there exist symmetries in the theory that allow one of the righthanded neutrinos to become naturally massless, making it a candidate for the sterile neutrino discussed in the literature. Departures from the exact bimaximal limit leads to ...
متن کاملCosmological constraints on a light non-thermal sterile neutrino
Although the MiniBooNE experiment has severely restricted the possible existence of light sterile neutrinos, a few anomalies persist in oscillation data, and the possibility of extra light species contributing as a subdominant hot (or warm) component is still interesting. In many models, this species would be in thermal equilibrium in the early universe and share the same temperature as active ...
متن کاملSearch for a light sterile neutrino at Daya Bay.
A search for light sterile neutrino mixing was performed with the first 217 days of data from the Daya Bay Reactor Antineutrino Experiment. The experiment's unique configuration of multiple baselines from six 2.9 GW(th) nuclear reactors to six antineutrino detectors deployed in two near (effective baselines 512 m and 561 m) and one far (1579 m) underground experimental halls makes it possible t...
متن کاملFate of the Sterile Neutrino
In light of recent Super-Kamiokande data and global fits that seem to exclude both pure νμ → νs oscillations of atmospheric neutrinos and pure νe → νs oscillations of solar neutrinos (where νs is a sterile neutrino), we reconsider four-neutrino models to explain the LSND, atmospheric, and solar neutrino oscillation indications. We argue that the solar data, with the exception of the Cl results,...
