Hello,<br>
<br>
Are you actually showing Sigmas for Egamma from 1.1 to 2.1 GeV? The
way this is worded seems like you will be presenting data from the
entire range.<br>
<br>
The question of t-channel exchange for the omega isn't a question of
pseudoscalar vs scalar but of pseudoscalar vs Pomeron, and analysis
of differential cross-sections says that pion exchange is dominate
below 2 GeV.<br>
<br>
Being isospin 1/2 makes it useful in understanding the N* spectrum,
but saying it makes for cleaner data samples doesn't make sense.<br>
<br>
How are you going to decompose Sigma, which is a measure of the
asymmetry of the phi distribution of the meson, to get SDMEs, which
are a function of the decay pions?<br>

Hi all,
Please find attached Danny's abstract for the IX Latin American Symposium
for Nuclear Physics and Applications. Danny was have some trouble mailing
this to the group. We would ask for your input before it gets circulated
to the HS PWG.
Thanks,
Phil

Hi all,
I will be presenting very preliminary results for the photon beam
asymmetry for the g8b data at the July IX Latin American Symposium on
Nuclear Physics and Applications.
I appreciate any comments.
