TL;DR
This paper explores adding backreacting flavor branes to the Klebanov-Witten model using AdS/CFT, providing new solutions and guidelines for extending to other N=1 SCFTs and massive flavors.
Contribution
It introduces a new backreacted flavor brane solution in Type IIB supergravity and generalizes the method for all N=1 SCFTs on D3-branes at Calabi-Yau cones.
Findings
Consistent match between supergravity solutions and field theory expectations.
Generalized method for adding flavors to N=1 SCFTs.
Guidelines for incorporating massive flavor branes.
Abstract
Using AdS/CFT, we study the addition of an arbitrary number of backreacting flavors to the Klebanov-Witten theory, making many checks of consistency between our new Type IIB plus branes solution and expectations from field theory. We study generalizations of our method for adding flavors to all N=1 SCFTs that can be realized on D3-branes at the tip of a Calabi-Yau cone. Also, general guidelines suitable for the addition of massive flavor branes are developed.
