γ* γ* scattering via secondary Reggeon exchange in QCD Academic Article uri icon

abstract

  • We summarize the results on the high energy behavior of quark–antiquark exchange in γ*γ* elastic scattering. The ladder diagrams, summed in the double logarithmic approximation, provide a perturbative QCD model for secondary reggeon exchange.
