The Double Spin Asymmetry for Exclusive $\pi^{+}$ Production With CLAS

The eg1b run was conducted using CLAS at Jefferson Lab using a 1.6 GeV - 5.6 GeV longitudinally polarized electron beam and polarized nuclear targets (composed of NH$_{3}$ and ND$_{3}$). This analysis is of the double spin asymmetry $A_{et}$ in the exclusive production of positive pions from a polarized proton ($ep\rightarrow e\pi^{+}n$). The double spin asymmetry was measured as a function of the four kinematic variables $W$, $Q^{2}$, $\cos\theta ^{*}$ (the angle between the direction of the virtual photon and the produced pion), and $\phi^{*}$ (the angle between the lepton interaction plane and the hadron interaction plane). The value of this asymmetry can be used to determine the spin structure of the resonances. A brief description of the experimental setup will be given, and preliminary results will be shown.
