Abstract: We discuss diffractive photon production of vector mesons in holographic QCD. At large $\sqrt{s}$, the QCD scattering amplitudes are reduced to the scattering of pairs of dipoles exchanging a closed string or a pomeron. We use the holographic construction in a 5-dimensional anti-deSitter space (${\mathrm{Ad}S}_{5}$) to describe both the intrinsic dipole distribution in each hadron, and the pomeron exchange. Our results for the heavy meson photon production are made explicit and compared to some existing experiments.
