Flaxino dark matter and stau decay
Eung Jin Chun, Hang Bae Kim, Kazunori Kohri +1
If the spontaneous breaking of Peccei-Quinn symmetry comes from soft supersymmetry breaking, the fermionic partners of the symmetry-breaking fields have mass of order the gravitino…
Axino Light Dark Matter and Neutrino Masses with R-parity Violation
Eung Jin Chun, Hang Bae Kim
Motivated by the recent observation of the 511 keV -ray line emissions from the galactic bulge and an explanation for it by the decays of light dark matter particles, we conside…
Cosmological implication of antisymmetric tensor field on D-brane
Inyong Cho, Eung Jin Chun, Hang Bae Kim +1
We discuss the cosmological implications of an antisymmetric tensor field when it experiences a kind of ``Higgs mechanism,'' including nonlocal interaction terms, on D-branes. Even…
Cosmology of Antisymmetric Tensor Field in D-brane Universe
Eung Jin Chun, Hang Bae Kim, Yoonbai Kim
We analyze homogeneous, anisotropic cosmology driven by a self-interacting ``massive'' antisymmetric tensor field which is present in string theories with D-branes. Time-d…
Gravitino creation by an oscillating scalar field
David H. Lyth, Hang Bae Kim
This paper has been withdrawn because the analytic estimates are not confirmed by the numerical calculation of Nilles, Peloso and Sorbo (hep-ph/0102264 and hep-th/0103202).
Cosmological constraints on a Peccei-Quinn flatino as the lightest supersymmetric particle
Eung Jin Chun, Hang Bae Kim, David H. Lyth
In an interesting class of models, non-renormalizable terms of the superpotential are responsible for the spontanteous breaking of Peccei-Quinn (PQ) symmetry as well as the generat…
