Unquenched massive flavors and flows in Chern-Simons matter theories

Understand

We construct a holographic dual to the three-dimensional ABJM Chern-Simons matter theory with unquenched massive flavors.

• The flavor degrees of freedom are introduced by means of D6-branes extended along the gauge theory directions and delocalized in the internal space.
• To find the solution we have to solve the supergravity equations of motion with the source terms introduced by the D6-branes.
• The background we get is a running solution representing the renormalization group flow between two fixed points, at the IR and the UV, in both of which the geometry is of the form AdS_4 x M_6, where M_6 is a six-dimensional compact manifold.
