Dilaton stabilization and inflation in the D-brane world

초록

We study possible mechanisms of the dilaton stabilization in the D-brane world in which a compactified D-brane constitutes our universe. The dilaton can be stabilized due to the interplay between the D-brane tension and the negative scalar curvature of extra dimensions. Cosmic evolution of the dilaton is investigated with the obtained dilaton potential and it is found that inflation can be realized before the settlement of the dilaton.
