Graviton Cosmology in Universal Extra Dimensions
Jonathan L. Feng, Arvind Rajaraman, Fumihiro Takayama
In models of universal extra dimensions, gravity and all standard model fields propagate in the extra dimensions. Previous studies of such models have concentrated on the Kaluza-Kl…
SuperWIMP Dark Matter Signals from the Early Universe
Jonathan L. Feng, Arvind Rajaraman, Fumihiro Takayama
Cold dark matter may be made of superweakly-interacting massive particles, superWIMPs, that naturally inherit the desired relic density from late decays of metastable WIMPs. Well-m…
Superweakly Interacting Massive Particles
Jonathan L. Feng, Arvind Rajaraman, Fumihiro Takayama
We investigate a new class of dark matter: superweakly-interacting massive particles (superWIMPs). As with conventional WIMPs, superWIMPs appear in well-motivated particle theories…
