Galactic 511 keV line from MeV millicharged dark matter
Ji-Haeng Huh, Jihn E. Kim, Jong-Chul Park +1
We present a possible explanation of the recently observed 511 keV -ray anomaly with a new ``millicharged'' fermion. The new fermion is light () but has nev…
Axino as Cold Dark Matter Candidate
Jihn E. Kim
The possibility of the CDM axino is presented. From the early days of supersymmetry, axino has been considered as hot dark matter and warm dark matter. But the CDM axino has been c…
A Theoretical Review of Axion
Jihn E. Kim
It is emphasized that the existence of a very light axion is consistent with the strong CP invariance and cosmological and astrophysical constraints. The attempt to embed the very…
Lifetime Limit of LSP from Cosmological Light Elements
Jihn E. Kim
From the present cosmic abundance of the light elements, one can obtain a lifetime bounds of LSP. From the consideration of deuterium, we obtain s.
Axion Theory Review
Jihn E. Kim
I review the axion physics with emphases on the couplings of the very light axion and a possible realization in superstring models.
Cosmic Axion
Jihn E. Kim
I review the axionic solution of the strong CP problem and current status of the cosmic axion search.
