Higgs-Portal and Z'-Portal Dark Matters in Brane-World Cosmologies
… DM model within the framework of 5-dimensional brane-world cosmology. In this setup, our familiar 3-dimensional space is realized as a hyper-surface embedded in a 4-dimensional space. Within this context, all SM and DM fields are confined to the hyper-surface, while the graviton resides in the …

Dark matter searches with cosmic-ray detectors and the Square Kilometre Array
… theories are considered as well. Indeed, brane fluctuations, dubbed branons, are new degrees of freedom appearing in flexible brane-world models. These new fields behave as standard weakly interacting massive particles with a significant associated thermal relic density and would explain …

Unusual Matter Models in Cosmology
… cosmology, loop quantum gravity, k-essence, and brane-world cosmologies. We find a range of exact solutions for isotropic universes, discuss their behaviours with reference to the early- and late-time evolution, accelerated expansion, and the occurrence or avoidance of singularities. We briefly …

The origin of inflation.
… this point we consider a Randall-Sundrum (RS) brane world analogue of trace anomaly driven inflation, in which our universe is regarded as a domain wall in five dimensional anti-de Sitter (AdS) space with a large N conformal field theory living on the wall. It is shown that the effects of the …
