Leptogenesis via Resonant Sequential Dominance and TBC3 Mixing in a Type-I Seesaw Model
Michael Fodroci, Teruyuki Kitabayashi
We demonstrate how phenomenological model construction assuming Sequential Dominance can be extended to cases with degenerate right-handed neutrino masses. Because this framework a…
WIMP/FIMP dark matter and primordial black holes with memory burden effect
Teruyuki Kitabayashi, Amane Takeshita
The lifetime of primordial black holes (PBHs), which formed in the early universe, can be extended by the memory burden effect. Light PBHs may exist today and be candidates for dar…
Reply to "Comment on `Unified neutrino mixing and approximate reflection symmetry'[arXiv:2603.00885]''
Yuta Hyodo, Teruyuki Kitabayashi
Huang and Li [arXiv:2603.00885] have raised the following two points regarding our previous work [arXiv:2502.18029]:(1) The real-value conditions associated with - reflecti…
Dirac mass matrix textures and the lightest right-handed neutrino mass scale in Type I seesaw leptogenesis
Shuta Kosuge, Teruyuki Kitabayashi
The type I seesaw mechanism is one of the leading proposed explanations for how neutrinos acquire their tiny masses. However, the mass scale of the undiscovered right-handed neutri…
Modified TM2 for Reproducing All Best-Fit Values of Neutrino Mixing Angles
Michael Fodroci, Teruyuki Kitabayashi
As measurements of neutrino mixing angles continue to become more precise, it is increasingly likely that in the very near future a realistic neutrino mixing model will be required…
Running scalar spectral index in warm natural inflation
Teruyuki Kitabayashi, Aya Shimizu
The validity of inflation models is mainly evaluated according to the consistency of the predicted scalar spectral index , the tensor scalar ratio , and the runn…
