Holography of the Conformal Window

Understand

Inspired by the model of Jarvinen and Kiritsis, we present a simple holographic model for the on set of chiral symmetry breaking at the edge of the conformal window in QCD in the Veneziano limit.

• Our most naive model enforces the QCD two loop running coupling on a D3/D7 holographic brane system.
• The mass of the holographic field, describing the chiral condensate in the model, is driven below the BF bound when the running is sufficiently strong, triggering chiral symmetry breaking for N_f/N_c<2.9.
• This model though contains too great a remnant of supersymmetry and does not correctly encode the perturbative anomalous dimensions of QCD.
