There are a few issues that you should be aware of, particularly if there are questions from someone who knows the subject well. The prediction labeled NLO is a firm QCD prediction. This does not apply to the LO term which is only correct in the chiral limit. The Ioffe calculation is only a partial prediction since it only takes the contribution of the eta meson into account and neglects the contribution of the eta’ meson which contributes ~ 1/3 of the effect. </div><div class=""><br class=""></div><div class="">I’m enclosing my CD15 contribution which also comments on the pi0 lifetime and briefly summarizes our RMP review article. </div><div class=""><br class=""></div><div class="">regards,</div><div class="">Aron</div><div class=""><br class=""></div><div class="">Aron M.
