Stability of RS brane for tachyonic scalars
Kazuo Ghoroku
We study the stability of the RS brane embedded in the AdS vacuum of 5d gauged supergravity, where many tachyonic scalars exist. We consider a model in which these scalars coup…
Instability of thick brane worlds
Kazuo Ghoroku, Masanobu Yahiro
We examined 5d thick brane worlds constructed by a real scalar field. The solutions are obtained in terms of a simple form of smooth warp factor. For the case of dS brane, we found…
Gauge symmetry and cosmological constant on a brane
Kazuo Ghoroku, Nobuhiro Uekusa
We have examined the localization of gauge bosons on the three-brane embedded in 5D bulk space-time, and we find two kinds of branes on which both graviton and gauge bosons can be…
Nonlinear sigma model and Yang-Mills theory through non-critical string
Kazuo Ghoroku
We consider two-dimensional nonlinear sigma model from the viewpoint of the holography, which has been applied to the study of the Yang-Mills theory, based on the non-critical stri…
Interactions of two D-branes and String--D-brane with Quantum Correction
Kazuo Ghoroku
This paper has been withdrawn by the author due to a misunderstanding.
Effective Potential in String Induced Action
Kazuo Ghoroku, Kazunari Kaneko
The dynamical properties of the gauge theory of Born-Infeld type action, which is expected as the high-energy effective theory, are investigated by adding a complex scalar field to…
