First Measurement of the Double Spin Asymmetry in $\vec{e}\vec{p}\to e^{\prime }{\pi }^{+}n$ in the Resonance Region

CLAS Collaboration, R. De Vita

The double spin asymmetry in the $\vec{e}\vec{p}\to e^{\prime }{\pi }^{+}n$ reaction has been measured for the first time in the resonance region for four-momentum transfer $Q^2=0.35-1.5$ GeV$^2…
