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…
A Unified View of RS Braneworlds
Sugumi Kanno, Jiro Soda
There are various different descriptions of Randall-Sundrum (RS) braneworlds. Here we present a unified view of the braneworld based on the gradient expansion approach. In the case…
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…
Born-Again Braneworld
Sugumi Kanno, Misao Sasaki, Jiro Soda
We propose a cosmological braneworld scenario in which two branes collide and emerge as reborn branes with signs of tensions opposite to the original tensions of respective branes.…
