Abstract
We consider the Newton's force law for brane world consisting of periodic c onfiguration of branes. We show that it supports a massless graviton. Furth ermore, this massless mode is well separated from the Kaluza-Klein spectrum by a mass gap. Thus most of the problems in phenomenology coming from cont inuum of Kaluza-Klein modes without mass gap are potentially cured in such a model.
