On The Higher Codimension Braneworld
Sugumi Kanno, Jiro Soda
We study a codimension 2 braneworld in the Einstein-Gauss-Bonnet gravity. In the linear regime, we show the conventional Einstein gravity can be recovered on the brane. While, in t…
Braneworld Cosmology
Jiro Soda, Sugumi Kanno
We present a general formalism for studying an inflationary scenario in the two-brane system. We explain the gradient expansion method and obtain the 4-dimensional effective action…
Gravitational Waves from Rotating Black Strings
Sugumi Kanno, Jiro Soda
In the Randall-Sundrum two-brane model (RS1), a Kerr black hole on the brane can be naturally identified with a section of rotating black string. To estimate Kaluza-Klein (KK) corr…
A Novel Approach to Braneworld
Jiro Soda, Sugumi Kanno
Evaluating Kaluza-Klein (KK) corrections is indispensable to test the braneworld scenario. In this report, we propose a novel symmetry approach to an effective 4-dimensional action…
Effective Teukolsky Equation on the Brane
Sugumi Kanno, Jiro Soda
To estimate Kaluza-Klein (KK) corrections on gravitational waves emitted by perturbed rotating black strings, we give the effective Teukolsky equation on the brane which is separab…
Inflationary Braneworld Driven By Bulk Scalar Field
Jiro Soda, Sugumi Kanno
We have developed a formalism to study an inflationary scenario driven by a bulk inflaton in the two-brane system. The 4-dimensional low energy effective action is obtained using t…
