Extraction of beam-spin asymmetries from the hard exclusive ${\pi }^{+}$ channel off protons in a wide range of kinematics

S. Diehl, K. Joo, A. Kim +135

We have measured beam-spin asymmetries to extract the $\sin \varphi$ moment $A_{LU}^{\sin \varphi }$ from the hard exclusive $\vec{e}p\to e^{\prime }n{\pi }^{+}$ reaction above the resonance region, fo…
