Two-photon-exchange contribution to proton form factors in both space-like and time-like regions

摘要：

The two two-photon exchange corrections to the unpolarized cross section and polarized observable PT,PL in elastic ep scattering are discussed in a simple hadronic model.Comparing with previous results,theΔ contribution are re-analysed.And the similar corrections in e+e-→ p(p-)are also discussed.
