Polarization Phenomena in Small-Angle Photoproduction of e+e- Pairs and the Gerasimov-Drell-Hearn Sum Rule

A. I. L'vov, S. Scopetta, D. Drechsel +1

Photoproduction of $e^{+}{e}^{-}$ pairs at small angles is investigated as a tool to determine the functions $f_1$ and $f_2$ entering the real-photon forward Compton scattering amplitude…
