Branon Phenomenology

In brane-world models with low tension, the fluctuations of the brane along the extra dimensions (branons) are the only relevant new low-energy modes. Such branon fields are in general massive, stable and weakly interacting, and accordingly they are natural candidates to explain the universe missing mass problem. On the other hand, the branon phenomenology is very rich because they couple to all the Standard Model particles. Distinctive branon signals could be observed in next colliders and in dark matter searches.
