We pay especial attention to brane world models with low tension where the only relevant degrees of freedom at low energies are the Standard Model (SM) particles and the branons, which are transversal brane oscillations. By using an effective Lagrangian, we study some phenomenological consequences of these scenarios in a model independent way.engjournal articlehttp://dx.doi.org/10.1063/1.1594340http://www.aip.orghttp://arxiv.org/abs/hep-ph/0301009open access53Extra DimensionsGoldstone BosonsHierarchyFísica (Física)22 Física
