<div class="moz-cite-prefix">It is very nice data and an interesting
talk.<br>
<br>
I have a couple of suggestions:<br>
<br>
slide 1: The title is awfully long for a 10min talk. I suggest to
shorten it to something like (or similar)<br>
"Measurement of polarization observables in hyperon
photoproduction off bound neutrons".<br>
<br>
slide 5: The table is from the 2014 edition. A new edition RPP
2016 is now available online which has an <br>
updated version of that table (find table here:
<a class="moz-txt-link-freetext" href="http://pdg.lbl.gov/2016/reviews/rpp2016-rev-n-delta-resonances.pdf">http://pdg.lbl.gov/2016/reviews/rpp2016-rev-n-delta-resonances.pdf</a>).<br>
There are significant differences, e.g. N(1710)1/2+ *** =>
**** (also based on g + p -> K + Lambda), and <br>
photoproduction data are more emphasized over pion induced data.
<br>
<br>
slide 9: The D13(1900) has become P13(1900) or better N(1900)3/2+.
So, the comparison w/ and w/o <br>
D13 is not relevant anymore. There is, however, a new state
N(1875)3/2- that likely has different hadronic and <br>
photocouplings than what was assumed in the calculations for
"D13(1900)". I suggest to delete the two bullets on D13<br>
and refer to the two models as using different resonances and
parameters as ingredients. It makes little difference <br>
as none of the curves is close to the data except for the two
lowest energy bins near threshold, where P ~ 0. <br>
<br>
slide 14: bullet #4: .. calculations from are observed .... is
incomplete sentence. <br>
bullet #5: "Di fferences between data on free
proton and quasi-free<br>
neutron are observed that could be due to reaction
dynamics or<br>
other resonances." <br>
=> These differences may also be due to the
difference in isospin, <br>
<br>

Dear Colleagues,<br>
<br>
Please find attached Colin's contributed talk at the DNP meeting.
Let him know if you have any comments or suggestions.<br>
<br>
Best regards, Yordanka<br>
