Modular invariance and neutrino mixing
Tatsuo Kobayashi, Naoya Omoto, Yusuke Shimizu +3
We study the phenomenological implications of the modular symmetry of lepton flavors facing recent experimental data of neutrino oscillations. The mass matrices o…
Electric dipole moments and dark matter in a CP violating MSSM
Tomohiro Abe, Naoya Omoto, Osamu Seto +1
We investigate electric dipole moments (EDMs) in a CP-violating minimal supersymmetric standard model with the Bino-like neutralino dark matter (DM) annihilating through the heavy…
Radiative Kähler moduli stabilization
Tatsuo Kobayashi, Naoya Omoto, Hajime Otsuka +1
We propose a new type of Kähler moduli stabilization mechanisms in type IIB superstring theory on Calabi-Yau manifolds with the positive Euler number. The overall Kähler modulus ca…
Supersymmetry preserving and breaking degenerate vacua, and radiative moduli stabilization
Tatsuo Kobayashi, Naoya Omoto, Hajime Otsuka +1
We propose a new type of moduli stabilization scenario where the supersymmetric and supersymmetry-breaking minima are degenerate at the leading level. The inclusion of the loop-cor…
Constraints on small-field axion inflation
Tatsuo Kobayashi, Akane Oikawa, Naoya Omoto +2
We study general class of small-field axion inflations which are the mixture of polynomial and sinusoidal functions suggested by the natural and axion monodromy inflations. The axi…
Small field axion inflation with sub-Planckian decay constant
Kenji Kadota, Tatsuo Kobayashi, Akane Oikawa +3
We study an axion inflation model recently proposed within the framework of type IIB superstring theory, where we pay a particular attention to a sub-Planckian axion decay constant…
Entropy production by domain wall decay in the NMSSM
Hironori Hattori, Tatsuo Kobayashi, Naoya Omoto +1
We consider domain walls in the symmetric NMSSM. The spontaneous discrete symmetry breaking produces domain walls, and the stable domain walls are problematic. Thus, we…
Dilution of axion dark radiation by thermal inflation
Hironori Hattori, Tatsuo Kobayashi, Naoya Omoto +1
Axions in the Peccei-Quinn (PQ) mechanism provide a promising solution to the strong CP problem in the standard model of particle physics. Coherently generated PQ scalar fields cou…
Possible altitudinal, latitudinal and directional dependence of relativistic Sagnac effect in Chern-Simons modified gravity
Daiki Kikuchi, Naoya Omoto, Kei Yamada +1
Toward a test of parity violation in a gravity theory, possible effects of Chern-Simons (CS) gravity on an interferometer have been recently discussed. Continuing work initiated in…
