Abstract
We report the first measurements of the beam-target helicity asymmetry for the , and channels in the energy range 1.702.34 GeV. The CLAS system at Jefferson Lab uses a circularly polarized photon beam and a target consisting of longitudinally polarized solid molecular hydrogen deuteride with low background contamination for the measurements. The multivariate analysis method boosted decision trees was used to isolate the reactions of interest. Comparisons with predictions from the KaonMAID, SAID, and Bonn-Gatchina models are presented. These results will help separate the isospin and photo-coupling transition amplitudes in pseudoscalar meson photoproduction.
