Baryonic branches and resolutions of Ricci-flat Kahler cones

Understand

We consider deformations of N=1 superconformal field theories that are AdS/CFT dual to Type IIB string theory on Sasaki-Einstein manifolds, characterised by non-zero vacuum expectation values for certain baryonic operators.

• Such baryonic branches are constructed from (partially) resolved, asymptotically conical Ricci-flat Kahler manifolds, together with a choice of point where the stack of D3-branes is placed.
• The complete solution then describes a renormalisation group flow between two AdS fixed points.
• We discuss the use of probe Euclidean D3-branes in these backgrounds as a means to compute expectation values of baryonic operators.
