Late decaying axino as CDM and its lifetime bound
Hang-Bae Kim, Jihn E. Kim
The axino with mass in the GeV region can be cold dark matter(CDM) in the galactic halo. However, if R-parity is broken, for example by the bilinear terms , then axino($\tilde…
Cosmology of Randall-Sundrum models
Hang Bae Kim
There are many interesting issues in the brane world with a large/warped extra dimension. We focus on the cosmological aspects. We review the cosmological solutions of the brane wo…
A dark matter solution from the supersymmetric axion model
Sanghyeon Chang, Hang Bae Kim
We study the effect of the late decaying saxino (the scalar superpartner of the axion) and find out that there is a possible dark matter solution from a class of supersymmetric ext…
Dark Matters in Axino Gravitino Cosmology
Eung Jin Chun, Hang Bae Kim, Jihn E. Kim
It is suggested that the axino mass in the 1 MeV region and gravitino mass in the eV region can provide an axino lifetime of order of the time of photon decoupling. In this case, s…
