[G14_run] Abstract for NStar 2017

[Nicholas Zachariou]

Hi Haiyun, 


See below for some minor corrections/comments in parenthesis:
Single and double asymmetries (use polarisation observables instead?) play key roles of understanding the single meson photoproduction. Recently, a paper reported the first beam-target double-polarization asymmetries with circular beam in the γn(p) → π−p(p) reaction in the nucleon resonance region. This talk presents the first beam-target double-polarization asymmetries (observable) with linear (linearly polarized photon) beam in the same reaction and the same energy region by the same group (be specific on energy region and I would remove the “by the same group”). Linearly polarizaed (polarized) photons and longitudinally polaized (polarized) deuterons in (a) solid hydrogen deuteride (HD) (target) have been used (in Hall-B that houses  the ) CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson lab. Different beam and target polarization  (orientations were)  combined to extract beam (Σ) and beam-targe (target) (G) asymmetries. The Σ observables (singular) are (is) consistent with published results. The (energy and angular dependence of ) results of G and its comparison with model prediction is reported.
