Bouncing pre-big bang on the brane

Abstract

A regular bouncing universe is obtained in the context of a dilaton-gravity brane world scenario. The scale factor starts in a contracting inflationary phase both in the Einstein and in the string frame, it then undergoes a bounce (due to interaction with the bulk Weyl tensor), and subsequently enters into a decelerated expanding era. This graceful exit is obtained at low curvature and low coupling, and without violating the Null Energy Condition.

16 pages, 3 figures; final version to be published on PRD. General improvement of section II (better specification of the matter content on the brane and discussion about the late time behavior), main results unchanged; 2 references added
