英文摘要The contributions of two-photon exchange in the process e(+) + e(-) -> p + (p) over bar including N and Delta intermediate states are estimated in a simple hadronic model The corrections to the unpolarized cross section as well as to the polarized observables P(x) and P(z) are evaluated. The results show the corrections to unpolarized cross section are small and the angle dependence becomes weak at small s after considering the N and Delta(1232) contributions simultaneously, while the correction to P(z) is enhanced
