Probing heavy neutrinos in the COMET experiment
Takehiko Asaka, Atsushi Watanabe
We argue that the COMET experiment --- a dedicated experiment for the - conversion search --- can be a powerful facility to search for heavy neutrinos in the mass range $1\,{…
The spectrum and flavor composition of the astrophysical neutrinos in IceCube
Atsushi Watanabe
We fit the energy distribution of the IceCube starting events by a model which involves four parameters in the neutrino spectrum, namely three normalizations and a co…
Dark matter and U(1)' symmetry for the right-handed neutrinos
Manfred Lindner, Daniel Schmidt, Atsushi Watanabe
We consider a U(1)' gauge symmetry acting on three generations of right-handed neutrinos. The U(1)' symmetry is broken at the TeV scale and its remnant discrete symmetry makes one…
Reproducing lepton mixing in a texture zero model
Luís Lavoura, Werner Rodejohann, Atsushi Watanabe
We note that the emerging features of lepton mixing can be reproduced if, with inverted neutrino mass ordering, both the smallest neutrino mass and the element of the neutrino…
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…
