Branon radiative corrections to collider physics and precision observables

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

In the context of brane-world scenarios, we study the effects produced by the exchange of virtual massive branons. A one-loop calculation is performed which generates higher-dimensional operators involving SM fields suppressed by powers of the brane tension scale. We discuss constraints on this scenario from colliders such as HERA, LEP and Tevatron and prospects for future detections at LHC or ILC. The most interesting phenomenology comes from new four-particles vertices induced by branon radiative corrections, mainly from four fermion interactions. The presence of flexible branes modifies also the muon anomalous magnetic moment and the electroweak precision observables.
