Flavor brane on the baryonic branch of moduli space

TL;DR

This paper investigates the addition of a flavor D7-brane to a cascading gauge theory, demonstrating supersymmetry preservation across the baryonic branch of moduli space, with potential implications for gauge/string duality.

Contribution

It provides a supersymmetric D7-brane embedding solution on the baryonic branch, extending understanding of flavor branes in complex gauge theory backgrounds.

Findings

D7-brane preserves supersymmetry everywhere on the baryonic branch.

Solution to the kappa-symmetry equation confirms mutual supersymmetry.

Potential applications in gauge/string duality and flavor physics.

Abstract

We study an extra flavor in the cascading SU((k+1)M)xSU(k M) gauge theory by adding probe D7-brane to the geometry. By finding a solution to the kappa-symmetry equation we establish that the D7-brane is mutually supersymmetric with the background everywhere on the baryonic branch of moduli space. We also discuss possible applications of this result.
