Axion braneworld cosmology
Cosimo Bambi, Masahiro Kawasaki, Federico R. Urban
We study axion cosmology in a 5D Universe, in the case of flat and warped extra dimension. The comparison between theoretical predictions and observations constrains the 5D axion d…

Gravitational production of KK states
Cosimo Bambi, Federico R. Urban
Gravitational particle production in the context of braneworlds is considered from a phenomenological point of view. The production of KK modes for bulk fields is discussed and the…

Gravitational particle production in braneworld cosmology
C. Bambi, F. R. Urban
Gravitational particle production in time variable metric of an expanding universe is efficient only when the Hubble parameter is not too small in comparison with the particle…
