Linear Sigma Models of H and KK Monopoles

TL;DR

This paper develops a gauged linear sigma model for H-monopoles and explores its T-dual KK-monopoles, clarifying the concept of the winding coordinate in string theory.

Contribution

It introduces a new gauged linear sigma model for H-monopoles and provides a detailed analysis of its T-dual KK-monopoles, including the interpretation of winding coordinates.

Findings

Gauged linear sigma model for H-monopoles constructed

T-dual model describes KK-monopoles with clarified winding coordinate

Enhanced understanding of monopole dualities in string theory

Abstract

We propose a gauged linear sigma model of k H-monopoles. We also consider the T-dual of this model describing KK-monopoles and clarify the meaning of "winding coordinate" studied recently in hep-th/0507204.
