Thanks, I did answer the question by saying that they got as far as
a BR and that it is a difficult measurement.<br>

ChPT calculation on eta' is less precise compared to eta because
of a large mass. In order to test ChPT, one needs a precision
measurement of Dalitz distribution, which is missing in the
BESIII result.</div>

There was a question from Jan Friedrich (COMPASS/AMBER),
concerning the BESIII result on eta'-> pi0gg, along the
lines of, do we know more now about ChPT?
<br>
<br>
The session chair, <span role="heading" aria-level="1"
class="x_yKMVIe">Zein-Eddine Meziani, said he was pleased to
see the studies of eta(') et al. mesons to come along at
JLab. Come to think of it, that is the point I was trying to
make.

The talk would to a large part report on the JEF physics
program and light meson TFFs. I would also like to advertise
the planned pi0 TFF experiment in Hall B.
<br>
<br>
I hope that is ok! <br>

Thx, <br>
