Decaying dark matter with heavy axino
Ji-Haeng Huh, Jihn E. Kim
A TeV scale decaying dark matter chiral multiplet N is introduced in addition to the minimal supersymmetric standard model(MSSM). For a calculable abundance of N, we introduce heav…
The minimal two DM components with SUSY
Ji-Haeng Huh, Jihn E. Kim, Bumseok Kyae
We present the dark matter extension of the minimal supersymmetric standard model by one more two component stable fermion N toward explaining the recent rising high energy positro…
Updated Axion CDM energy density
Ji-Haeng Huh
We update cosmological bound on axion model. The contribution from the anharmonic effect and the newly introduced initial overshoot correction are considered. We present an explici…
511 keV -ray emission from the galactic bulge by MeV millicharged dark matter
Ji-Haeng Huh, Jihn E. Kim, Jong-Chul Park +1
We propose a possible explanation for the recently observed anomalous 511 keV line with a new "millicharged" fermion. This new fermion is light []. Nevertheles…
Two dark matter components in N_{DM}MSSM and dark matter extension of the minimal supersymmetric standard model and the high energy positron spectrum in PAMELA/HEAT data
Ji-Haeng Huh, Jihn E. Kim, Bumseok Kyae
We present the dark matter (DM) extension (by N) of the minimal supersymmetric standard model to give the recent trend of the high energy positron spectrum of the PAMELA/HEAT exper…
Update of axion CDM energy density
Kyu Jung Bae, Ji-Haeng Huh, Jihn E. Kim
We improve the estimate of the axion CDM energy density by considering the new values of current quark masses, the QCD phase transition effect and a possible anharmonic effect.
