Abstract

We propose a modified mode-expansion of the bulk fields in a BPS domain wall background to obtain the effective theory on the wall. The broken SUSY is nonlinearly realized on each mode defined by our mode-expansion. Our work clarifies a relation between two different approaches to derive the effective theory on a BPS wall, \it i.e. the nonlinear realization approach and the mode-expansion approach. We also discuss a further modification that respects the Lorentz and U(1)_R symmetries broken by the wall.
