Unstable D-branes and String Cosmology
Chanju Kim, Hang Bae Kim, Yoonbai Kim +2
Cosmological implication of rolling tachyons is reported in the context of effective field theory. With a brief review of rolling tachyons in both flat and curved spacetimes, we st…
Cosmology of Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study dynamics of rolling tachyon and Abelian gauge field on unstable D-branes, of which effective action is given by Born-Infeld type nonlocal action. Possible cosmological evo…
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This paper has been withdrawn because the analytic estimates are not confirmed by the numerical calculation of Nilles, Peloso and Sorbo (hep-ph/0102264 and hep-th/0103202).
Coupling Constant Unification and LEP Data
Hang Bae Kim, Jihn E. Kim
The recent LEP data for gauge coupling constants constrain many grand unified models. In this paper, we study several possibilities for unification of gauge coupling constants. Wit…
