Description

We construct an approximate holographic dual of QCD. Conformal symmetry breaking and other IR effects are described by deformations of the anti-de Sitter background metric. This framework allows us to reproduce the empirically found square-mass trajectories of universal slope for radially and orbitally excited hadrons. We furthermore investigate whether linear trajectories for excited mesons can be related to the area-law confinement criterion for the Wilson loop, and how to obtain the underlying bulk metric as a solution of the five-dimensional Einstein equation
