Low Energy Noncommutativity in Deformed Randall-Sundrum Space-Time — Thorsten Ohl, Alexander Schenkel, and •Christoph Uhlemann — Institut für Theoretische Physik und Astrophysik, Universität Würzburg

We construct noncommutative (NC) deformations of the Randall-Sundrum space-time that solve NC Einstein equations with a Poisson tensor depending on the radial coordinate. In a class of these deformations where the Poisson tensor is exponentially localized towards one of the branes (the NC-brane), we study the effects on bulk particles in terms of effective operators induced by NC-brane interactions. We give two examples where massive bulk particles mediate NC effects from the NC brane to an almost-commutative SM brane.
