Flavor quark at high temperature from a holographic model
Kazuo Ghoroku, Tomohiko Sakaguchi, Nobuhiro Uekusa +1
Gauge theory with light flavor quark is studied by embedding a D7 brane in a deconfinement phase background newly constructed. We find a phase transition by observing a jump of the…
Chiral symmetry breaking driven by dilaton
Kazuo Ghoroku, Masanobu Yahiro
Dynamical properties of gauge theories with light flavor quarks are studied in a dual supergravity by adding a D7-brane probe into the AdS background deformed by the dilaton. By es…
Radius stabilization and brane running in RS1 model
Iver Brevik, Kazuo Ghoroku, Masanobu Yahiro
We study the effective potential of a scalar field based on the 5D gauged supergravity for the RS1 brane model in terms of the brane running method. The scalar couples to the brane…
Effective action and brane running
Iver Brevik, Kazuo Ghoroku, Masanobu Yahiro
We address the renormalized effective action for a Randall-Sundrum brane running in 5d bulk space. The running behavior of the brane action is obtained by shifting the brane-positi…
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…
Newton's law in de Sitter brane
Kazuo Ghoroku, Akihiro Nakamura, Masanobu Yahiro
Newton potential has been evaluated for the case of dS brane embedded in Minkowski, dS and AdS bulks. We point out that only the AdS bulk might be consistent with the N…
