Soliton Gauge States and T-duality of Closed Bosonic String Compatified on Torus

TL;DR

This paper explores soliton gauge states in bosonic string theory compactified on a torus, revealing their connection to enhanced gauge symmetries and T-duality at specific moduli points.

Contribution

It demonstrates the relationship between soliton gauge states, enhanced Kac-Moody gauge symmetry, and T-duality in torus-compactified bosonic strings.

Findings

Soliton gauge states are linked to enhanced gauge symmetries.

T-duality is related to the existence of these soliton states.

Enhanced Kac-Moody symmetry occurs at specific moduli points.

Abstract

We study soliton gauge states in the spectrum of bosonic string compatified on torus. The enhenced Kac-Moody gauge symmetry, and thus T-duality, is shown to be related to the existence of these soliton gauge states in some moduli points.
