Cross sections and beam asymmetries for $\vev{e}p \to enπ^+$ in the nucleon resonance region for $1.7\le Q^2\le 4.5(GeV{)}^2$

K. Park, V. D. Burkert, W. Kim +1

The exclusive electroproduction process $\vec{e}p\to e^{\prime }n{\pi }^{+}$ was measured in the range of the photon virtuality $Q^2=1.7-4.5\mathrm{Ge}{\mathrm{V}}^2$, and the invariant mass range…
