| 英文摘要 | Two-photon annihilate contributions in the process e(+) + e(-) p + (p) over bar including N and Delta intermediate are discussed in a simple hadronic model. The corrections to the Unpolarized cross section and polarized observables P-x, P-z are presented. The results show the two-photon annihilate correction to Unpolarized cross section is small and its angle dependence becomes weak at small s after considering the IN and Delta(1232) contributions Simultaneously, while the correction to Pz is enhanced.
