Description
Diffractive scattering of photons with large momentum transfer is measured
for the first time at HERA, with the H1 detector. Cross-sections are
presented as a function of W, the photon-proton centre of mass energies,
and t, the square of the four-momentum transferred at the proton vertex.
Results are compared to a model based on pQCD using LLA approximation of
the BFKL evolution.
