Description of the spacelike and timelike proton form factors at large momentum transfer in the QCD factorization approach
چکیده انگلیسی
We propose QCD factorization approach for description of the soft spectator scattering contribution. It is expected that such contribution is very important for description of the many exclusive processes at moderate values of Q2. Assuming the dominance of this mechanism we provide qualitative consideration of the proton form factors in the spacelike and timelike regions. Using the same approach we also provide estimates of the cross sections for the processes γγ→pp̄ and pp̄→γγ at large energy and momentum transfer.
