  In brane-world models with low tension, massive branons are natural
candidates for dark matter. The phenomenology of these WIMP-like particles is
completely determined by their mass, the brane tension and, in the case of
effects due to radiative corrections, by the cutoff setting the scale of
validity of the branon effective theory. In this paper, we review the main
constraints on branon physics coming from colliders, astrophysics and
cosmological observations, and include more recent limits obtained from
electroweak precision measurements.
