# Charge asymmetry and symmetry properties - High Energy Physics - Phenomenology

Abstract: Applying general symmetry properties of electromagnetic interaction,information from electron proton elastic scattering data can be related tocharge asymmetry in the annihilation channels $e^++e^-\leftrightarrow \bar p +p$ and to the ratio of the cross section of elastic electron and positronscattering on the proton. A compared analysis of the existing data allows todraw conclusions on the reaction mechanism.
