Target and beam-target spin asymmetries in exclusive pion electroproduction for \(Q^2>1\) GeV\(^2\). II. \(e p \rightarrow e \pi^0 p\)

Target and beam-target spin asymmetries in exclusive pion electroproduction for \(Q^2>1\) GeV\(^2\). II. \(e p \rightarrow e \pi^0 p\)

Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive \(\pi^0\) electroproduction reaction \(\gamma^* p \to p \pi^0\), expanding an analysis of the \(\gamma^* p \to n \pi^+\) reaction from the same experiment. The results were obtained from scattering...

Zusammenfassung:Beam-target double-spin asymmetries and target single-spin asymmetries were measured for the exclusive \(\pi^0\) electroproduction reaction \(\gamma^* p \to p \pi^0\), expanding an analysis of the \(\gamma^* p \to n \pi^+\) reaction from the same experiment. The results were obtained from scattering of 6 GeV longitudinally polarized electrons off longitudinally polarized protons using the CEBAF Large Acceptance Spectrometer at Jefferson Lab. The kinematic range covered is \(1.1
