Electroproduction of Protons in the Forward Direction

Abstract

We present data on electroproduction off protons in which a proton moving in approximately the same direction as the virtual photon is detected. Measurements were made at data points with ($Q^2$, $W$) values of (0.6, 2.67), (1.2, 2.67), (2.0, 2.67), and (1.2, 2.15) in (Ge${\mathrm{V}}^2$, GeV). The virtual photoproduction cross section for $p$+MM is studied as a function of scaling variables $x^{\prime }$ and ${P_{\perp }}^2$, azimuthal angle $\varphi$, $Q^2$, and $W$.
