Dear all,<br>
<br>
During the last eta/eta' meeting I presented some slides which can
be found here:<br>
<br>
<a
href="https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3996">https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3996</a><br>
<br>
We had a discussion about the differences between the two histograms
on slide 6 (the black distributions should be the same and they are
not). <br>
<br>
This problem was not due to a scaling factor as we suspected. There
was a bug in the script that I am using to analyze the generated
events. I was accidentally cutting away some of the generated events
for the eta pi0 pi0 Monte Carlo. After correcting this bug the two
distributions are identical.<br>
<br>
This also means that the efficiency (and therefore the cross
section) that was extracted for the eta pi0 pi0 final state was
wrong. I will correct the relevant files and update the cross
section results accordingly.<br>
<br>
Kind regards,<br>
George<br>
