A few comments on the high-energy behavior of string scattering amplitudes in warped spacetimes

TL;DR

This paper investigates the high-energy behavior of string scattering amplitudes in warped spacetimes, showing that if the theory is finite, the amplitudes decrease as powers of momentum across all orders of perturbation.

Contribution

It provides a comprehensive analysis of string scattering in warped spacetimes and demonstrates the power-law falloff of amplitudes assuming finiteness.

Findings

Amplitudes fall as powers of momentum at high energies.

The analysis is valid to all orders in perturbation theory.

Finiteness of the theory implies specific high-energy behavior.

Abstract

The high-energy behavior of string scattering in warped spacetimes is studied to all orders in perturbation theory. If one assumes that the theory is finite, the amplitudes exactly fall as powers of momentum.
