Wilson-line Scalar as a Nambu-Goldstone Boson in Flux Compactifications and Higher-loop Corrections

Masaki Honda, Toshihide Shibasaki

We study a scalar zero mode originated from extradimensional components of a gauge field in a six-dimensional theory compactified on a magnetized torus. We confirm it is a Nambu-Go…

Relaxation of hierarchy in higher-dimensional Starobinsky model

Yu Asai

Starobinsky model, which has a Ricci scalar squared term $R^{2}$ in its action, is one of the most promising inflation models from the viewpoint of Cosmic Microwave Background obse…

Behaviors of two supersymmetry breaking scales in $N = 2$ supergravity

Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1

We study the supersymmetry breaking patterns in four-dimensional $N = 2$ gauged supergravity. The model contains multiple (Abelian) vector multiplets and a single hypermult…

Revisiting instabilities of $S^{1} / Z_{2}$ models with loop-induced Fayet-Iliopoulos terms

Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1

We study Fayet-Iliopoulos (FI) terms of 5-dimensional supersymmetric $U (1)$ gauge theory compactified on $S^{1} / Z_{2}$ . In this model, loop diagrams including matter hypermultiplets an…

Scalar-metric-affine theories: Can we get ghost-free theories from symmetry?

Katsuki Aoki, Keigo Shimada

We reveal the existence of a certain hidden symmetry in general ghost-free scalar-tensor theories which can only be seen when generalizing the geometry of the spacetime from Rieman…

Heterotic Stringy Corrections to Metrics of Toroidal Orbifolds and Their Resolutions

Pompey Leung, Hajime Otsuka

We explicitly analyse $O (α^{'})$ corrections to heterotic supergravity on toroidal orbifolds and their resolutions, which play important roles in string phenomenology as well as modul…

Wavefunctions on $S^{2}$ with flux and branes

Sosuke Imai, Yoshiyuki Tatsuta

We formulate a six dimensional $U (1)$ gauge theory compactified on a (two dimensional) sphere $S^{2}$ with flux and localized brane sources. Profiles of the lowest Kaluza-Klein (KK)…

Interpolation of partial and full supersymmetry breakings in $N = 2$ supergravity

Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1

We discuss an $N = 2$ supergravity model that interpolates the full and the partial supersymmetry breakings. In particular, we find the conditions for an $N = 0$ Minkowski…

Matrix model and Yukawa couplings on the noncommutative torus

Masaki Honda

The IKKT model is proposed as a non-perturbative formulation of superstring theory. We propose a Dirac operator on the noncommutative torus,which is consistent with the IKKT model,…
