The Effect of Extra Dimension on Dark Matter
Nobuchika Okada, Osamu Seto
We investigate the thermal relic density of a cold dark matter in the brane world cosmology. Since the expansion law in a high energy regime is modified from the one in the standar…
Neutralino dark matter in brane world cosmology
Takeshi Nihei, Nobuchika Okada, Osamu Seto
The thermal relic density of the neutralino dark matter in the brane world cosmology is studied. Since the expansion law at a high energy regime in the brane world cosmology is mod…
A brane world cosmological solution to the gravitino problem
Nobuchika Okada, Osamu Seto
We investigate the thermal production of gravitinos in the context of the brane world cosmology. Since the expansion law is modified from the one in the standard cosmology, the Bol…
Phenomenology of TeV Right-handed Neutrino and the Dark Matter Model
Kingman Cheung, Osamu Seto
In a model of TeV right-handed (RH) neutrino by Krauss, Nasri, and Trodden, the sub-eV scale neutrino masses are generated via a 3-loop diagram with the vanishing see-saw mass forb…
D-term Inflation and Nonperturbative Kahler Potential of Dilaton
Tetsutaro Higaki, Tatsuo Kobayashi, Osamu Seto
We study the -term inflation scenario with a nonperturbative Kähler potential of the dilaton field. Although the FI term which leads an inflationary expansion is given by the de…
