[Primex] meeting

[Aron Bernstein]

Dear Ashot and all,

     Following yesterday’s discussion about the pi0 paper I agree that a strong conclusion should be presented in the abstract. My suggestion is to add a last sentence in the abstract:

This is consistent with the theoretical prediction which is dominated by the QCD axial anomaly plus a 4.8% chiral correction.

I also want to reiterate my suggestion that that the only theoretical lines that should be shown in Fig. 1 are the axial anomaly and the chiral perturbation prediction. This experiment is important because there is a QCD prediction that should be accurately tested. The graph as it is now presented does not make this point. It implies that there is a theoretical uncertainty that in fact does not exist. As it now stands Fig. 1 diminishes the impact of our experiment- this is why I have raised this point so forcefully.

Regards,
Aron
