Quantum effects on a thick de Sitter brane Masato Minamitsuji (YITP/Osaka) with Wade Naylor (RITS) & Misao Sasaki (YITP) hep-th/0508093+@
Motivation Bulk inflaton model An inflation model in the context of braneworld Randall-Sundrum setup (warped extra-dimension & infinitely thin brane) + 5D scalar field (an inflaton) 4D type inflation + KK modes Issues; How large is the quantum backreaction of KK modes / bulk gravitons?
A problem about quantum effects Surface divergence Quantum effects of KK modes suffer divergences on the brane. We discuss… How do we regularize it? One possible solution: Taking effects of the brane thickness into account “Can the finite thickness of the brane regularize the surface divergence? ” In details, please come and see my poster.
