Scattering of String Monopoles

TL;DR

This paper studies the scattering behavior of string monopoles, showing that in the low-velocity limit, their interactions are trivial and can be described by geodesic motion on a flat moduli space.

Contribution

It provides the first calculation of the moduli space metric for multimonopole solutions in heterotic string theory, revealing a flat metric at leading order.

Findings

Multimonopole solutions exhibit trivial scattering behavior.

The moduli space metric is flat to leading order in impact parameter.

Results align with test monopole predictions.

Abstract

In the low-velocity limit, multi-soliton solutions trace out geodesics in the static solution manifold with distance defined by a metric on moduli space. For the recently constructed multimonopole solutions of heterotic string theory, we obtain a flat metric to leading order in the impact parameter. This result agrees with the trivial scattering predicted by a test monopole calculation.
