Scientific paper

We study particle production at the collision of two domain walls in 5-D Minkowski spacetime. This may provide the reheating mechanism of an ekpyrotic brane universe [1]. We evaluate a production rate of particles confined to the domain wall. The reheating temperature is evaluated as TR approx 0.88 bar g N¼b. In order to have the baryogenesis at the electro-weak energy scale, the fundamental mass scale is constrained as mη ~ 1.1 × 107 GeV for bar g ~ 10-5.
