A Problem in Virtual Graviton exchanges in Flat Large Extra Dimensions
The paper says
“To search for the signal of the large extra dimensions with high energy collider experiments, we need more care in interpreting the earlier results on the cross sections of these processes.”

The paper
Abstract
It is pointed out in a class of models with large extra dimensions that the cross section of processes with virtual Kaluza-Klein graviton exchanges becomes either much smaller or much larger by many orders of magnitude than what is expected from that of the on-shell production of the Kaluza-Klein gravitons. We demonstrate how the problem arises using a toy model. The cause of this new problem lies in the fact that we do not have momentum conservation in the extra dimensions. To search for the signal of the large extra dimensions with high energy collider experiments, we need more care in interpreting the earlier results on the cross sections of these processes.

However, as we will see below, the cross section of such processes in past works (for example in Ref. [ref] ) does not satisfy the approximate expression in eq.([ref]).

The cross section in eq.([ref]) reproduces the result that we get using the $i ϵ$ method or the principal value integration of the propagators to regularize the on-shell pole divergence of KK scalars ( for more details, see Ref. [ref] )[ The leading terms in the two methods correspond the result assuming $$ and $Γ(m)$ in the denominator in eq.([ref]) to be zero.].
