Geometric scaling in exclusive processes
arXiv:hep-ph/0303211 · doi:10.1140/epjc/s2003-01294-1
Abstract
We show that according to the present understanding of the energy evolution of the observables measured in deep-inelastic scattering, the photon-proton scattering amplitude has to exhibit geometric scaling at each impact parameter. We suggest a way to test it experimentally at HERA. A qualitative analysis based on published data is presented and discussed.
