"+-+" Brane Model Phenomenology

Abstract

We explore the phenomenology of the recently proposed "+-+" brane model which has a characteristic anomalously light first Kaluza-Klein mode. We consider the processes e^+ e^- to mu^+ mu^- and the Kaluza-Klein production e^+ e^- to gamma KK giving missing visible energy. These in combination with the latest Cavendish experiments place severe bounds on the parameter space of the model. We also discuss how forthcoming experiments can test the model for ``natural'' range of the parameters.
