Zero-mode product expansions and higher order couplings in gauge backgrounds
Masaki Honda, Tatsuo Kobayashi, Hajime Otsuka
We study a four-dimensional low-energy effective field theory derived from extra dimensional field theories with general gauge backgrounds. We find that products among fermionic ze…
On Lorentz-invariant spin-2 theories
Atsushi Naruko, Rampei Kimura, Daisuke Yamauchi
We construct Lorentz-invariant massless/massive spin-2 theories in flat spacetime. Starting from the most generic action of a rank-2 symmetric tensor field whose Lagrangian contain…
Polonyi-Starobinsky supergravity with inflaton in a massive vector multiplet with DBI and FI terms
Hiroyuki Abe, Yermek Aldabergenov, Shuntaro Aoki +1
We propose the Starobinsky-type inflationary model in the matter-coupled four-dimensional supergravity with the massive vector multiplet that has inflaton (scalaron) and gold…
-attractor-type Double Inflation
Kei-ichi Maeda, Shuntaro Mizuno, Ryota Tozuka
We study the background dynamics and primordial perturbation in -attractor-type double inflation. The model is composed of two minimally coupled scalar fields, where each of the…
Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity
Hiroyuki Abe, Yermek Aldabergenov, Shuntaro Aoki +1
We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infel…
heterotic standard model vacua in general Calabi-Yau compactifications
Hajime Otsuka, Kenta Takemoto
We study a direct flux breaking scenario in heterotic string theory on general Calabi-Yau threefolds. The direct flux breaking, corresponding to hypercharge flux breaking…
Quark mass matrices in magnetized orbifold models with localized Fayet-Iliopoulos terms
H. Abe, T. Kobayashi, S. Takada +2
We study magnetized orbifold models. We assume the localized Fayet-Iliopoulos terms and the corresponding gauge background. Such terms lead to strong localization of zero-mode wave…
superfield description of BPS solutions in 6D gauged SUGRA with 3-branes
Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1
We provide superfield description of BPS backgrounds in six-dimensional supergravity (6D SUGRA) with 3-branes, which is compactified on a two-dimensional space. The br…
Effects of localized μ-terms at the fixed points in magnetized orbifold models
Hiroyuki Abe, Makoto Ishida, Yoshiyuki Tatsuta
We consider magnetized orbifolds, where the supersymmetric mass term for a pair of up- and down-type Higgs (super)fields, called -term, is localized at the orbifold fixed points…
Ghost-free scalar-fermion interactions
Rampei Kimura, Yuki Sakakihara, Masahide Yamaguchi
We discuss a covariant extension of interactions between scalar fields and fermions in a flat space-time. We show, in a covariant theory, how to evade fermionic ghosts appearing be…
S-matrix Unitarity and Renormalizability in Higher Derivative Theories
Yugo Abe, Takeo Inami, Keisuke Izumi +2
We investigate the relation between the -matrix unitarity () and the renormalizability, in theories with negative norm states. The relation has been confirmed in…
SO(32) heterotic line bundle models
Hajime Otsuka
We search for the three-generation standard-like and/or Pati-Salam models from the heterotic string theory on smooth, quotient complete intersection Calabi-Yau threefolds…
