Deep-inelastic electroproduction of pions in a quark-parton model

Abstract

Invariant cross sections for the processes $\mathrm{ep}\to e{\pi }^{\pm }+\mathrm{anything}$ are calculated in a quark-parton model. We use a wave-function formalism which we show to be equivalent to the Kuti-Weisskopf quark-parton model of hadrons. Imposing simplifying assumptions valid for a high-momentum final state, we obtain good agreement with existing experimental data.
