I am not aware of what are the analysis details that will be part of the big g12 note. However, bear in mind that TCS has quite a peculiar final state, with an electron-positron pair, which may be unusual for photoproduction analyses, and as such may require its own set of PID and fiducial cuts, different from the g12 standards. But, once again, I have really no idea of what the big g12 note contains.<br>
If you decide to "freeze" the review, make sure to inform the author, who may be working on our comments.<br>
Btw, the majority of our comments were on aspects that are very specific of that channel (acceptance corrections, observables extracted, physics conclusions, etc), so I don't think there can be overlap with Eugene's & co's work.<br>
Regards,<br>
Silvia<br>

> In my view, to benefit from the large amount of work that your committee has put into this review, I would favour blocking the further progress of any g12 review (spectroscopy or deep processes) until your committee has concluded its charge. That way, the collaboration can be assured that all g12 analyses were treated equally. I hope that a consequence of this will be to encourage communication within the g12 run group.<br>
