Description
We present a three-dimensional holographic picture of the pion in which both confinement and chiral symmetry breaking play important roles. We show that the internal transverse and longitudinal light-front QCD dynamics in the pion map onto the IR and UV limits of the scalar field equation of motion in 5-dimensional anti de Sitter spacetime (AdS) deformed by a quadratic dilaton. While conformal symmetry is explicitly broken on the AdS side for transverse dynamics, it is explicitly broken on the QCD side for longitudinal dynamics.
