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…
Toward pole inflation and attractors in supergravity : Chiral matter field inflation
Tatsuo Kobayashi, Osamu Seto, Takuya H. Tatsuishi
In string-inspired supergravity theory, Kähler metric of chiral matter fields often has a pole. Such Kähler metric is interesting from the viewpoint of the framework of the pole in…
Non-perturbative moduli superpotential with positive exponents
Hiroyuki Abe, Tetsutaro Higaki, Tatsuo Kobayashi +1
We study non-perturbative moduli superpotentials with positive exponents, i.e. the form like with a positive constant and the modulus . These effects can be genera…
Dynamical solutions of warped six dimensional supergravity
Edmund J. Copeland, Osamu Seto
We derive a new class of exact time dependent solutions in a warped six dimensional supergravity model. Under the assumptions we make for the form of the underlying moduli fields,…
Inflation in uplifted Supergravities
B. de Carlos, J. A. Casas, A. Guarino +2
We present a model of slow-roll inflation in the context of effective Supergravities arising from string theories. The uplifting of the potential (to generate dS or Minkowski vacua…
Gravitational waves in cosmological models of Hořava-Witten theory
Osamu Seto, Hideo Kodama
We study the behavior of gravitational waves and their backreaction on the background in cosmological solutions of the five-dimensional Hořava-Witten theory. As a dynamical backgro…
