Hyper-Scaling Relations in the Conformal Window from Dynamic AdS/QCD

Understand

Dynamic AdS/QCD is a holographic model of strongly coupled gauge theories with the dynamics included through the running anomalous dimension of the quark bilinear, gamma.

• We apply it to describe the physics of massive quarks in the conformal window of SU(N_c) gauge theories with N_f fundamental flavours, assuming the perturbative two loop running for gamma.
• We show that to find regular, holographic, renormalization group flows in the infra-red the decoupling of the quark flavours at the scale of the mass is important and enact it through suitable boundary conditions when the flavours become on shell.
• We can then compute the quark condensate and the mesonic spectrum (M_rho, M_pi, M_sigma) and decay constants.
