Measurement of the Inclusive Electroproduction of Hadrons

The electroproduction of hadrons was studied with a wide-aperture spectrometer. Inclusive data are presented for the electron-scattering region $-0.5>q^2>-2.5\mathrm{}{\left(\frac{\mathrm{GeV}}{c}\right)}^2$, $4<\mathrm{}\nu <14\mathrm{}$ GeV. Distributions of the electroproduced hadrons in the three inclusive variables $\varphi$, ${p_{\perp }}^2$, and $x$ are studied in the region $x>\mathrm{}0\mathrm{}$. A striking difference from photoproduction is observed in the excess of positive over negative hadrons at high $x$ and high $q^2$.
