A multidimensional study of the structure function ratio \(\sigma_{LT'}/\sigma_{0}\) from hard exclusive \(\pi^+\) electro-production off protons in the GPD regime

A multidimensional extraction of the structure function ratio \(\sigma_{LT'}/\sigma_{0}\) from the hard exclusive \(\vec{e} p \to e^\prime n \pi^+\) reaction above the resonance region has been performed. The study was done based on beam-spin asymmetry measurements using a 10.6 GeV incident ele...

Description
Summary:A multidimensional extraction of the structure function ratio \(\sigma_{LT'}/\sigma_{0}\) from the hard exclusive \(\vec{e} p \to e^\prime n \pi^+\) reaction above the resonance region has been performed. The study was done based on beam-spin asymmetry measurements using a 10.6 GeV incident electron beam on a liquid-hydrogen target and the CLAS12 spectrometer at Jefferson Lab. The measurements focus on the very forward regime (\(t/Q^{2}\) \(\ll\) 1) with a wide kinematic range of \(x_{B}\) in the valence regime (0.17 \(
