Query: Virtual photon scattering at high energies as a probe of the short
  distance pomeron   Perturbative QCD predicts the behavior of scattering at high energies and
fixed (sufficiently large) transferred momenta in terms of the BFKL pomeron (or
short distance pomeron). We study the prospects for testing these predictions
in two-photon processes at LEP200 and a possible future e+ e- collider. We
argue that the total cross section for scattering two photons sufficiently far
off shell provides a clean probe of BFKL dynamics. The photons act as color
dipoles with small transverse size, so that the QCD interactions can be treated
perturbatively. We analyze the properties of the QCD result and the possibility
of testing them experimentally. We give an estimate of the rates expected and
discuss the uncertainties of these results associated with the accuracy of the
present theoretical calculations.
