Low-Energy Dynamics of String Solitons

TL;DR

This paper studies the low-energy behavior of fivebrane string solitons, showing they do not interact at low energies due to a flat moduli space metric, implying trivial scattering.

Contribution

It demonstrates that the moduli space metric for these solitons is flat, leading to non-interacting low-energy dynamics, which is a new insight into their behavior.

Findings

Moduli space metric is flat for these solitons

Solitons do not interact at low energies

Scattering is trivial at low energies

Abstract

The dynamics of a class of fivebrane string solitons is considered in the moduli space approximation. The metric on moduli space is found to be flat. This implies that at low energies the solitons do not interact, and their scattering is trivial. The range of validity of the approximation is also briefly discussed.
