| contents | We present a novel derivation of the full holographic conformal anomaly in two five-dimensional scalar-tensor theories-one Lovelock-Horndeski type and one Einstein-dilaton-Gauss-Bonnet-obtained via a unified mechanism for Kaluza-Klein reduction of the ten-dimensional heterotic string effective action. In the Lovelock-Horndeski case, we also construct exact asymptotically AdS solutions with linear dilaton profiles and establish a holographic a-theorem. Our results confirm the consistency of AdS/CFT in the presence of non-minimal scalar couplings and higher curvature terms, and show how string-theoretic modifications control the emergence of conformal anomalies and constrain the RG structure of dual field theories. |
