It is not a good idea to present a laundry list at an international conference. It would be better that you could focus on physics and the status of data analysis in general. I would suggest making changes as the following:</div>

due to spontaneous breaking of the chiral symmetry by the QCD vacuum at the massless quark limit; and the decay of η into two photons is mainly driven by the chiral anomaly. A precision measurement of the η-->2g decay width will offer determinations of the
light quark-mass ratio and the η-η' mixing angle in model independent manners. There has been a longstanding discrepancy (~4σ) between the previous experimental results using Primakoff and e+e- collisions. The PrimEx-eta experiment is aimed at a new measurement
via the Primakoff effect to resolve this discrepancy. A full statistical data was already collected at JLab through three different run periods in the past several years. The status of data analysis will be presented in this talk.</span></p>

Hi Igal,<br>
It is a good idea to present our results in this very important Conference.<br>
I have two suggestions:<br>
1) it is better to have both "the GlueX" and "the PrimEx-eta"<br>
collaboration names in the beginning of the abstract. That would be<br>
better.<br>
2) somehow, when I read the abstract it gives me a negative impression<br>
about the experiment. The first part of the text is emphasizing our<br>
internal "problems" with this experiment a little more than it is<br>
needed (to me). Those problems are very typical for ALL Primakoff<br>
types of experiments. To solve those "problems" people designed<br>
experiments with: (a) better angular resolution, and (b) cleaner beam<br>
line for lesser background.<br>
3) I would not promise a "precise result". This is a not needed<br>
obligation at this time.<br>
<br>
The rest is very good and I support the article.<br>
