The abstract, sentence by sentence
We calculate emission rates of various bosonic/fermionic soft massless states of open/closed superstring from an ensemble of a highly excited open/closed superstring in the flat background. The resulting spectrum shows thermal distributions at the Hagedorn temperature. We find greybody factors for each process and observe their relation to the ones from blackholes.

Original abstract
We calculate emission rates of various bosonic/fermionic soft massless states of open/closed superstring from an ensemble of a highly excited open/closed superstring in the flat background. The resulting spectrum shows thermal distributions at the Hagedorn temperature. We find greybody factors for each process and observe their relation to the ones from blackholes.

We thus conclude that we can use the results of [ref] in a warped background (under the usual assumptions), provided we modify the couplings and the effective string scale appropriately.

Having understood the relative strength of the interactions, in section [ref] we review the computation of the decay rate of a typical string into gravitons, which has been carried out in the bosonic [ref] and supersymmetric [ref] case at leading order in string perturbation theory in flat backgrounds.

(This fact has already been pointed out by Amati and Russo [ref] for the bosonic string case.) As for fermion emissions, $σ_FB$ is slightly different from the one calculated in [ref] by a factor of $ω$, which may be due to a formal $s$-wave limit discussed later, but the exponential factors are the same.
