Contribution

It constructs the DBI action for these D-branes using a specific two-form and verifies its consistency with conformal field theory results.

Findings

DBI action matches CFT predictions

Identifies singularities in branes covering the entire group

Provides detailed geometric analysis of the branes

Abstract

In this paper we study the non-maximally symmetric D-branes on the SU(2) group discussed in a previous article (hep-th/0205097). Using the two-form defined in hep-th/0205097 the DBI action on the branes is constructed. This action is checked for its agreement with CFT predictions. The geometry of the branes is analyzed in detail, and the singularities of branes covering the entire group are found.
