# String Production in the Abelian Higgs Vacuum

## TL;DR

This paper numerically investigates how classical Abelian-Higgs gauge field wavepackets produce strings, identifying conditions for prompt string formation from single or colliding wavepackets.

## Contribution

It introduces a numerical framework to study string production from wavepackets and maps the parameter space for string formation in Abelian-Higgs models.

## Key findings

- Single wavepackets can produce strings promptly under certain conditions.
- Colliding sub-critical wavepackets can generate strings in specific parameter regions.
- The study delineates parameter space regions conducive to string formation.

## Abstract

We numerically study string production by evolving classical Abelian-Higgs gauge field wavepackets. Initial conditions are constructed for the propagation of a single wavepacket and for the collision of two wavepackets. We identify regions of parameter space that lead to prompt production of strings from a single wavepacket. The collision of two sub-critical wavepackets can also lead to the production of strings in certain regions of parameter space.
