Scaling Dimensions in AdS/QCD and the Gluon Field Strength Propagator    [PDF]

Joshua W. Powell

We derive the scaling dimension of boundary operators in the AdS/CFT correspondence using a path integral treatment of the boundary-to-boundary propagators of their dual fields. We then apply the same technique to AdS/QCD where scaling dimensions are anomalous. In particular, we compute the two-point correlation function of gluon field strength operators, for which it is prerequisite to know the flow of the anomalous scaling dimension. The results are in very good agreement with quenched lattice QCD data, thus confirming the functional form of the scaling dimension.
