D-brane Interactions, World-sheet Parity and Anti-Symmetric Tensor

TL;DR

This paper demonstrates how world-sheet parity relates mixed D-string components to the anti-symmetric B-field, leading to the suppression or elimination of interactions between certain D-branes.

Contribution

It reveals a duality between mixed D-string components and the B-field, explaining interaction modifications via world-sheet parity.

Findings

Mixed D and N components are dual to the B-field.

The B-field reduces or removes interactions between dissimilar D-branes.

World-sheet parity underpins the duality and interaction effects.

Abstract

Using world-sheet parity we show that mixed D and N components of D-strings are dual to the anti-symmetric $B_{\mu\nu}$ field. The contribution of the latter is responsible for the reduction and even removal of all the interactions between two dissimilar D-branes.
