A Double-Dilaton Holographic Model of QCD: Running Coupling and Meson Phenomenology
Abstract
We present a holographic model of QCD to study the strong coupling constant αs from the low-energy region to the high-energy regime. The approach uses a double-dilaton background, which breaks conformal and chiral symmetries, while large-Nc corrections are incorporated to connect the holographic description with perturbative QCD. The model leads to an infrared fixed point and provides a smooth transition to the pQCD running. The resulting background also produces linear Regge trajectories for scalar, vector, and tensor states in reasonable agreement with experimental data.

The model leads to an infrared fixed point and provides a smooth transition to the pQCD running.
