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…
On the Flux Vacua in F-theory Compactifications
Yoshinori Honma, Hajime Otsuka
We study moduli stabilization of the F-theory compactified on an elliptically fibered Calabi-Yau fourfold. Our setup is based on the mirror symmetry framework including brane defor…
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…
Axion Inflation and Affleck-Dine Baryogenesis
Kensuke Akita, Tatsuo Kobayashi, Hajime Otsuka
String theory generically predicts the coupling between the Affleck-Dine field and axion field through higher-dimensional operators. We thus explore the Affleck-Dine baryogenesis o…
