抄録

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 ≈ 0.88 ḡ N1/4b. In order to have the baryogenesis at the electro-weak energy scale, the fundamental mass scale is constrained as m η ∼ 1.1 × 107 GeV for ḡ ∼ 10 -5.
