Summary
We use gauge/gravity duality to study deeply virtual Compton scattering
(DVCS) in the low x limit, where the process
is dominated by the exchange of the pomeron. At strong coupling, the pomeron is described
as the graviton Regge trajectory in AdS space, with a hard wall to mimic
confinement effects. This model agrees with HERA data in a large
kinematical range. The behavior of the DVCS cross section for very high
energies, inside saturation, can be explained by a simple AdS black disk
model. In a restricted kinematical window, this model agrees with HERA
data as well.
