Abstract: We discuss diffractive photon production of vector mesons in holographic QCD. At large 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 (AdS5) 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.
