Dear All,
<div class=""><br class="">
</div>
<div class="">First of all, best wishes for the New Year - I trust everyone had at least a reasonable break given the somewhat constraining circumstances of COVID.</div>
<div class=""><br class="">
</div>
<div class="">Please find below an email I received from Feng this afternoon in response to our email just before Christmas. My reading is that it would be good to start planning in earnest pretty soon so that we have a strong proposal whether there be two
or a combined one. I realize some of you are still on travel, but perhaps we should aim to have a call later this week, or early next? In the meantime, it would be good to start refining the material in the overleaf page, and in particular whether we can
“firm up the overall goals” any further.</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>
<div class="">David<br class="">

</div>
<div class="">Happy New Year!<br class="">
<div class=""><br class="">
</div>
<div class="">Thanks for your message and sorry for the late reply due to the end of the year activities. </div>
<div class=""><br class="">
</div>
<div class="">I did talk to Jianwei about Jlab's interest in GPDs and also talked to Xiangdong about his center</div>
<div class="">interest. I have lined up some people from BNL, MIT, UVa, MSU and other places. Our goal is mostly about </div>
<div class="">GPD, Winger functions extraction from experimental data both at Jlab and EIC, and lattice calculations. We will</div>
<div class="">work out a plan soon. It sounds like your effort has some overlap with us. Let's discuss</div>
<div class="">down the line how much overlap we have, and to see the pros and cons in joining the efforts. </div>
<div class=""><br class="">

<div class="">Best,<br class="">

Dear Feng and Xiangdong,<br class="">
<br class="">
Jianwei said earlier this week that you had been talking about the possibility of pulling together a team, focused on GPDs, to respond to the expected call for Topical Collaborations in Nuclear Theory. We’ve been having discussions about this focused both
on the physics, and on the potential to create university bridge positions. At the moment, we’ve had discussions amongst participants at ANL, JLab/Hampton/WM, Temple, UConn.<br class="">
<br class="">
In the case of the physics, we’ve formulated our ideas into the broad areas of<br class="">
<br class="">
a) QCD Theory, and experimental processes<br class="">
b) First-principles lattice QCD computations<br class="">
c) Global analysis/error quantification using lattice + experimental measures<br class="">
d) Implication for our understanding of internal structure of nucleons and nuclei<br class="">
<br class="">
The other aspect we’ve been focused on is the issue of bridge positions, and in practice this is the issue where time is most of the essence, given the need to engage with the administrations at the universities.<br class="">
<br class="">
Collectively, we all feel that a combined effort would provide an exceptionally strong proposal - none of us have seen the FOA, but certainly Tim Hallman has indicated that one focused on hadron structure would be a high priority, given the 12GeV data now emerging
and the future EIC. <br class="">
<br class="">
Regards,<br class="">
