Experimental Study of Nuclear Shadowing in Low-Q2Electroproduction

Abstract

The total cross section for hadron production by inelastic electron scattering at 3.2° from a number of nuclei has been measured at several virtual photon energies at fixed $Q^2=0.1\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$. The hadronic cross section is measured directly, by detecting at least one hadron in coincidence with the scattered electron. The results show very little shadowing and no detectable energy dependence. These observations contradict vector-meson dominance.
