Full higher-dimensional analysis of moduli oscillation and radiation in expanding universe
Hajime Otsuka, Yutaka Sakamura
We investigate effects of the radiation and the moduli oscillation around the stabilized values on the evolution of a 6-dimensional spacetime compactified on . In order to see…
Spacetime evolution during moduli stabilization in radiation dominated era beyond 4D effective theory
Hajime Otsuka, Yutaka Sakamura
We investigate the time evolution of the background spacetime during the moduli stabilization process, which is assumed to occur in the radiation dominated era. The setup is basica…
UV sensitivity of Casimir energy
Yu Asai, Yutaka Sakamura
We quantitatively estimate the effect of the UV physics on the Casimir energy in a five-dimensional (5D) model on . If the cutoff scale of the 5D theory is not far from th…
Fate of domain walls in 5D gravitational theory with compact extra dimension
Hiroyuki Abe, Shuntaro Aoki, Yu Asai +1
We pursue the time evolution of the domain walls in 5D gravitational theory with a compact extra dimension by numerical calculation. In order to avoid a kink-antikink pair that dec…
KK-mode contribution to the crossover scale for the brane-induced force
Yutaka Sakamura
We discuss contributions of the KK modes to the crossover length scale for the brane-induced force when the brane is given by a solitonic background field. We work in a…
Behaviors of two supersymmetry breaking scales in supergravity
Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1
We study the supersymmetry breaking patterns in four-dimensional gauged supergravity. The model contains multiple (Abelian) vector multiplets and a single hypermult…
