Pion and proton form factors in the Regge description of electroproduction $p(e,e^{\prime }{\pi }^{+})n$

Abstract

Electroproduction of ${\pi }^{+}$ above the resonance region is analyzed in the Regge model for $\pi +\rho$ exchanges. Importance of the roles of pion and proton form factors in the process is discussed in comparison with existing models of Kaskulov and Mosel, and of Vrancx and Rychebusch. It is shown that the present model with proton form factor of a simple dipole-type yields a better description of DESY and JLab data over those models for high $Q^2$ and $-t$ region up to 5 GeV${}^2$.
