<div><br>
</div>
<div>I am afraid to say that I cannot attend the g12 meeting today. I am sure that comparison g12 and g11 is important </div>
<div>but I feel that more important to compare g12 with published data (there are not much high energy brem data </div>
<div>available but there are CLAS g1c data which we published not long time ago. Please find attached plots which </div>
<div>show a perfect agreement between Mike Dugger's analysis (g1c) and Mike Kunkel one (g12).</div>
<div><br>
</div>
<div>Cheers, igor</div>

Michael and others,<br>
<br>
I will not be able to attend the g12 meeting today because of teaching duties. Zulkaida will contribute and represent FSU. In particular, we are interested in the discussion of the kinematic fitter with Kaons.<br>
<br>
We are also working on our FSU g12 analysis note and as mentioned several times before, we ran into this nasty acceptance problem for the ω channel owing to the (large off-center) target position. The ω cross sections for the forward and backward half of the
target differ by almost 15 - 20%. Michael, have you checked your cross section for a similar effect? At the moment, we are unsure how to proceed and how to account for this effect.<br>
<br>
For similar acceptance reasons, we consider our double-pion analysis (for the energy range 1.5 - 3.5 GeV) dead or at least suspended for the moment; the g12-data quality is simply not good enough (compared to g11a, for instance). The g12-data may also not be
good enough for the ω Dalitz-plot analysis, which may also affect other Dalitz-plot analyses. However, a conclusion has not been finalized. As Lei suggested, it would be good to compile a list of all analyses (and analysis notes) that would like to move forward.<br>
<br>
Best wishes,<br>
<br>
Volker<br>
