Query: 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 the this need
not mean that the result is mostly gravitons with negligible visible radiation
on the Standard Model brane. We show that if the inflationary throat is not too
strongly warped, and if the string coupling is sufficiently weak, then a
significant fraction of the energy density from annihilation will be deposited
on the Standard Model brane, even if it is separated from the inflationary
throat by being in some more deeply warped throat. This is due to the
exponential growth of the massive Kaluza-Klein wave functions toward the
infrared ends of the throats. We argue that the possibility of this process
removes a conceptual obstacle to the construction of multi-throat models,
wherein inflation occurs in a different throat than the one in which the
Standard Model brane resides. Such multi-throat models are desirable because
they can help to reconcile the scale of inflation with the supersymmetry
breaking scale on the Standard Model brane, and because they can allow cosmic
strings to be sufficiently long-lived to be observable during the present
epoch.
