Baryons with D5 Brane Vertex and k-Quarks
Kazuo Ghoroku, Masafumi Ishihara
We study baryons in SU(N) gauge theories, according to the gauge/string correspondence based on IIB string theory. The D5 brane, in which fundamental strings are dissolved as a…
D3/D7 holographic Gauge theory and Chemical potential
Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura
N=2 supersymmetric Yang-Mills theory with flavor hypermultiplets at finite temperature and in the dS are studied for finite quark number density () by a dual supergravit…
Holographic heavy-light mesons from non-Abelian DBI
Johanna Erdmenger, Kazuo Ghoroku, Ingo Kirsch
In the context of gauge/gravity duals with flavor, we examine heavy-light mesons which involve a heavy and a light quark. For this purpose we embed two D7 brane probes at different…
Flavor quarks in AdS4 and gauge/gravity correspondence
Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura
The non-perturbative properties of the gauge theories in the AdS are studied in the dual supergravity by including light flavor quarks, which are introduced by a D7 brane emb…
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…
