Using holography, we study the low-lying mesonic spectrum of a range of asymptotically free gauge theories. We utilise the 'Dynamic AdS/QCD model' in which the gauge theory dynamics is included by a choice for the running of the anomalous dimension. We consider models with quarks in the fundamental, adjoint, two-index symmetric and two-index anti-symmetric representations. We display predictions for M_rho, M_pi and M_sigma and compare with lattice results for quenched and 2+1 fundamental fermions for SU(3).
