<div><p>Dear Chair of the Hadron Spectroscopy Working Group,</p><p>Haiyun Lu, within the g14 group, has been working in the last few
years at the extraction of Sigma and G single and double
polarization observables for the pi+n photoproduction on
quasi-free neutron target, using data obtained from linearly
polarized photons impinging on the longitudinally polarized HD
target. Results on Sigma asymmetry are compared with the ones
obtained from g13 data, for consistency checks. The results on G
asymmetry are the first ever obtained.<br>
</p><p>A version of the analysis note is under internal final revision
of the g14 group and will soon be ready for the CLAS Collaboration
review, the title being:</p><p><span style="left: 105.684px; top: 217.255px; font-size:
