General analysis of polarization phenomena in $e^{+}+e^{-}\to N+\bar{N}$ for axial parametrization of two--photon exchange

Abstract

General properties of the differential cross section and of the polarization observables are derived for the $e^{+}+e^{-}\to N+\bar{N}$ reaction, in presence of two--photon exchange. Polarization effects are investigated for longitudinally polarized electron and polarized antinucleon and/or polarized nucleon in the final state. The single--spin asymmetry induced by the transverse polarization of the electron beam is also discussed.
