Multi-localization in multi-brane worlds

We study bulk fields in various multi-brane models with localized gravity. In the case of spin-0, 1/2 and 3/2 fields, the non-trivial background geome try itself can induce (multi-)localization of the zero modes along the extr a dimension. The addition of appropriate mass terms controls the strength o r/and the position of this localization and can induce (multi-)localization of spin-1 fields as well. We show that multi-brane models may also give ri se to anomalously light KK modes which are also localized. The possibility of multi-localization in the context of supersymmetric brane world models i n AdS(5) spacetime is also discussed. (C) 2001 Elsevier Science B.V. All ri ghts reserved.
