N2 - Bottom-up holographic models of QCD, inspired by the anti-de Sitter space/conformal field theory correspondence, have shown a remarkable degree of phenomenological success. However, they rely on a number of bold assumptions. We investigate the reliability of one of the key assumptions, which involves matching the parameters of these models to QCD at high 4D momentum q2 and renormalization scale μ2. We show that this leads to phenomenological and theoretical inconsistencies for scale-dependent quantities such as q̄q.
