Dark Matter Related to Axion and Axino
Jihn E. Kim
I discuss the essential features of the QCD axion: the strong CP solution and hence its theoretical necessity. I also review the axion and axino effects on astrophysics and cosmolo…
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…
Axions and the Strong CP Problem
Jihn E. Kim, Gianpaolo Carosi
Current upper bounds of the neutron electric dipole moment constrain the physically observable quantum chromodynamic (QCD) vacuum angle . Since QCD expla…
String Compactification and Unification of Forces
Jihn E. Kim
I review our recent attempts toward obtaining the MSSM from string orbifold compactification. The required constraints are the existence of three families and R parity, vectorlike…
