Warped reheating in brane–antibrane inflation

We examine how reheating occurs after brane–antibrane inflation in warped geometries, such as those which have recently been considered for type IIB string vacua. We adopt the standard picture that the energy released by brane annihilation is dominantly dumped into massive bulk (closed-string) modes which eventually cascade down into massless particles, but argue that this need not mean that the result is mostly gravitons with negligible …
