Loop Fayet-Iliopoulos terms in models: instability and moduli stabilization

Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1

We study Fayet-Iliopoulos (FI) terms of six-dimensional supersymmetric Abelian gauge theory compactified on a orbifold. Such orbifold compactifications can lead to locali…

Revisiting instabilities of models with loop-induced Fayet-Iliopoulos terms

Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1

We study Fayet-Iliopoulos (FI) terms of 5-dimensional supersymmetric gauge theory compactified on . In this model, loop diagrams including matter hypermultiplets an…

F-term Moduli Stabilization and Uplifting

Tatsuo Kobayashi, Osamu Seto, Shintaro Takada +3

We study Kähler moduli stabilization in IIB superstring theory. We propose a new moduli stabilization mechanism by the supersymmetry-braking chiral superfield which is coupled to K…

Poly-instanton axion inflation

Tatsuo Kobayashi, Shohei Uemura, Junji Yamamoto

We investigate the axion inflation model derived by poly-instanton effects in type II superstring theories. Poly-instanton effects are instanton effects corrected by another instan…

Massive higher spin fields in curved spacetime and necessity of non-minimal couplings

Masafumi Fukuma, Hikaru Kawai, Katsuta Sakai +1

Free massive higher spin fields in weak background gravitational fields are discussed. Contrary to the spin one case, higher spin fields should have nontrivial non-minimal coupling…
