抜粋

We study brane-world preheating in a massive chaotic inflationary scenario where Scalar fields are confined on the three-brane. Assuming that the quadratic contribution in energy densities dominates the Hubble expansion rate during preheating, the amplitude of the inflaton decreases slowly relative to the standard dust-dominated case. This leads to an efficient production of X particles via the nonperturbative decay of the inflaton even if its coupling is of the order of g = 10-5. We also discuss massive particle creation heavier than the inflaton, which may play an important role for baryogenesis and leptogenesis scenarios.
