A new dark matter candidate in low-tension brane-worlds
J. A. R. Cembranos, A. Dobado, A. L. Maroto
Brane world theories contain additional degrees of freedom related to the geometry of the extra dimension space which can be understood as brane oscillations (branons). In the case…
Branon dark matter
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In the brane-world scenario, our universe is understood as a three dimensional hypersurface embedded in a higher dimensional space-time. The fluctuations of the brane along the ext…
Living on a brane
J. A. R. Cembranos, A. Dobado, A. L. Maroto
We briefly review the distinctive signals of brane world models with low tension. We pay special attention to the brane fluctuations (branons), whose phenomenological consequences…
Goldstone bosons and solitons on the brane
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In this work we compute the effective action describing the low-energy brane Goldstone-boson dynamics. The Goldstone bosons or branons appear because the brane spontaneously breaks…
