Branes with Background Fields in Boundary State Formalism

TL;DR

This paper uses boundary state formalism to analyze brane interactions with background gauge fields, exploring effects of compactification and massless states, offering insights beyond traditional open string methods.

Contribution

It introduces a boundary state approach to study brane interactions with background fields, including effects of compactification and massless states, which are difficult to analyze with canonical methods.

Findings

Boundary state formalism effectively describes brane interactions with background gauge fields.

Compactification influences brane interaction dynamics.

Massless state contributions are significant in the interaction analysis.

Abstract

Interaction of branes in presence of internal gauge fields is considered by using the boundary state formalism. This approach enables us to consider the problems that are not easily accessible to the canonical approach via open strings. The effects of compactification of some of the dimensions on tori are also discussed. Also we study the massless state contribution on this interaction.
