Models in which our four-dimensional universe is a brane embedded in a higher-dimensional bulk, such as ADD large-extra-dimension scenarios and warped Randall–Sundrum geometries; covers their phenomenology (including black holes on the brane), collider or cosmic-ray signatures, and observational constraints.
