Diffractive Vector Photoproduction using Holographic QCD

Understand

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 pair of dipoles exchanging a closed string or a pomeron.
• We use the holographic construction in AdS$_5$ 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.
