Query: Non-BPS walls and their stability in 5d SUSY theory   We review recent work (hep-th/0404114) on non-BPS domain walls in $5d$ SUSY
theory. An exact solution of non-BPS multi-walls is found in supersymmetric
massive T*(CP1) model in five dimensions. The non-BPS multi-wall solution is
found to have no tachyon. The N=1 supersymmetry preserved on the
four-dimensional world volume of one wall is broken by the coexistence of the
other wall. The supersymmetry breaking is exponentially suppressed as the
distance between the walls increases.
