Abstract
We propose to test perturbative QCD(pQCD) in the Regge limit
by means of diffractive photon scattering,
, at large |t| and very high energies,
. The helicity amplitudes of this
process were calculated using the Lipatov solution of the BFKL
equation for
. We found that the perturbatively
calculated cross section for this process is comparable in
magnitude to
the cross section for
photoproduction assuming similar
kinematics.
