<div dir="ltr">Dear Taya,<div><br></div><div>Thank for your good slides. Unfortunately, your motivation, slide #2, is problematic </div><div>for me. You added the rescattering diagram to the impulse approximation and </div><div>assume that you selected two dominant diagrams which will work for your rho </div><div>photoproduction on the deuteron. I do not think so. Let me guess that you use </div><div>analogy with our analysis of the CLAS data for gd-->pi0d where critical role plays </div><div>a rescattering mechanism with eta-meson at intermediate state and taking into </div><div>account the fact that the first S11 has a huge BR in to etaN. That was good for </div><div>gd-->pi0d and allows to predict and describe a structure (close to the eta threshold) </div><div>in the excitation function for the backward scatting (no dibaryon contribution). </div><div>Unfortunately, your case is different. </div><div><br></div><div>I cannot advise how you can fix this slide but definitely, this slide is problematic </div><div>and nobody will buy it</div><div><br></div><div>Kind Regards, Igor</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div>-----</div><div>Igor Strakovsky, SAID CNS The George Washington University</div><div>Tel: 703-726-8344(NV),Skype: igors1945_2, Fax: 202-994-3001(FB),</div><div>Emails: <a href="mailto:igor@gwu.edu" target="_blank">igor@gwu.edu</a>, <a href="mailto:igor@jlab.org" target="_blank">igor@jlab.org</a></div></div></div></div></div></div></div></div>

<br>
I am going to give a contributed talk in the APS April Meeting, which is<br>
less than a week from now. My talk is titled "Coherent rho-meson<br>
photoproduction off deuterium from CLAS".<br>
<br>
This talk will present preliminary cross sections obtained from the g10<br>
data set. This utilizes fits about the &#961; peak within the invariant<br>
mass spectrum of the &#960;+&#960;&#8722; pair for bins in the 4-momentum<br>
transfer, t, as a function of E&#947;. This result will help improve<br>
understanding of nucleon scattering. In addition, this study is also<br>
important to understand the backgrounds in analyses of a possible d&#8727;<br>
dibaryon resonance that has the same final state.<br>
<br>

Any comments or suggestions would highly be appreciated.<br>
<br>
The talk is on Sunday, April 12th at 11:09 am.<br>
