Heavy neutrino search in accelerator-based experiments
Takehiko Asaka, Shintaro Eijima, Atsushi Watanabe
We explore the feasibility of detecting heavy neutrinos by the existing facilities of neutrino experiments. A heavy neutrino in the mass range 1 MeV < M < 500 MeV is produced by pi…
On the interpretation of IceCube cascade events in terms of the Glashow resonance
Atri Bhattacharya, Raj Gandhi, Werner Rodejohann +1
The IceCube experiment (IC) has recently observed 2 cascade events with energies between 1 and 10 PeV. This energy combined with the fact that no muon-track events are observed may…
Atmospheric Sterile Neutrinos
Takehiko Asaka, Atsushi Watanabe
We study production of sterile neutrinos in the atmosphere and their detection at Super-Kamiokande. A sterile neutrino in the mass range $1\,{\rm MeV} \lesssim M_N \lesssim 105\,{\…
Relating large to the ratio of neutrino mass-squared differences
Werner Rodejohann, Morimitsu Tanimoto, Atsushi Watanabe
The non-zero and sizable value of puts pressure on flavor symmetry models which predict an initially vanishing value. Hence, the tradition of relating fermion mixing matri…
