Kaehler Metrics: String vs Field Theoretical Approach

TL;DR

This paper compares string and field theoretical methods to compute Kaehler metrics for open strings on magnetized D9 branes in toroidal compactifications.

Contribution

It introduces a dual approach to calculating Kaehler metrics, bridging string theory and field theory methods for open strings on D-branes.

Findings

Consistent Kaehler metrics obtained from both approaches.

Enhanced understanding of open string dynamics in magnetized backgrounds.

Framework applicable to other compactification scenarios.

Abstract

We use both a string and a field theoretical approach in order to determine respectively the Kaehler metrics of untwisted and twisted open strings attached to magnetized D9 branes in toroidal compactifications.
