We study the possibility to explain the non-baryonic dark matter abundanceand improve the present fits on the muon anomalous magnetic moment through thesame new physics. The only viable way to solve simultaneously both problemswhich is known to date is by using supersymmetric theories. However in thiswork we show that massive brane fluctuations (branons) in largeextra-dimensions models can provide a more economical alternative tosupersymmetry. This is so because the low-energy branon physics dependseffectively on only three parameters. Next collider experiments, such as LHC orILC, will be sensitive to branon phenomenology in the natural parameter regionwhere the theory is able to account for the two effects.Comment: 4 pages, 3 figures, REVTeX
