The process eP --> eP gamma has been investigated by both the H1 and ZEUS c
ollaborations at HERA. Contributions beyond the normal QED Bethe-Heitler pr
ocess have been seen within the measurable kinematic range. These contribut
ions are consistent with a calculation of Deeply Virtual Compton Scattering
. A cross section, differential in Q(2) or W, has been measured by the H1 c
ollaboration and compared with this calculation.
