Dear all,<br>
I think having a meeting is a good idea.<br>
I will not be available on Thursday. What about Tuesday May 30 (any
time after 1:30PM CET)?<br>
Cheers<br>

Dear BDX colleagues,
<div>I write you concerning the message that Patrizia sent to the
JLab community, related to the white paper currently being
prepared to address the physics case for a 24 GeV energy upgrade
at Jefferson Laboratory (see below) According to Patrizia’s
message, the final goal is to have the white paper published on
a referred journal.</div>
<div><br>
</div>
<div>In Sec. 8.4, “secondary beams”, the projected sensitivity for
BDX@24 GeV is reported (see below). I think that having the
BDX@24 GeV projection included in this work is really important.
However, given that this result is going to be published in a
journal, and thus available for the whole community, I think
that, as BDX collaboration, we should discuss about how this
result was obtained, and also how this is described in the text.</div>
<div><br>
</div>
<div>For example, I think that in the text the fact that this is
only a preliminary estimate should be stated (where the
backgrounds at all evaluated)?</div>
<div> Same for the detector arrangement: was the BDX@24 GeV reach
computed assuming the same detector configuration (detector
dimensions and distance from the dump)? This cannot be the case,
since the increased muons energy will require more shielding to
range them out.</div>
<div><br>
</div>
<div>Finally, I find the format of this plot quite uncommon, since
the X axis is reported in a linear scale, and not log scale. </div>
<div><br>
</div>
<div>I think that it would be important to have a dedicated BDX
meeting for this next week. </div>
<div>What do you think about? Usually, we held BDX meetings on
Friday, but Friday June 2nd is holiday in Italy. What about
Thursday in the early afternoon?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Bests,</div>
<div>Andrea</div>

<div>Dear colleagues,<br>
<br>
You are receiving this message because you expressed<br>
<br>
support for or participated in one of the many workshops<br>
<br>
aimed at pursuing an energy upgrade to 22 GeV of CEBAF<br>
<br>
with the goal of advancing the frontiers of our knowledge<br>
<br>
across the spectrum of topics in nuclear physics. This<br>
<br>
high-impact program at the luminosity frontier will open<br>
<br>
up a rich and unique experimental nuclear physics program<br>
<br>
that combines illustrious history with an exciting<br>
<br>
scientific future.<br>
<br>
After a year of intensive workshops, the editorial committee<br>
<br>
has collected input from the community and assembled a<br>
<br>
White Paper that outlines an exciting scientific program<br>
<br>
for the future at Jefferson Lab. This document is openly<br>
<br>
available in the following link<br>

The initial author list contains the editorial committee<br>
<br>
as well as some others that have made direct contributions to
the<br>
<br>
document, but we recognize that many beyond this initial list<br>
<br>
are the creators of this program. This is a grass-roots effort<br>
<br>
that started with conversations amongst the recipients of this<br>
<br>
email. You have all contributed directly or indirectly through<br>
<br>
participation in discussions, providing comments, and asking<br>
<br>
questions. As such, we would like to invite you to sign the<br>
<br>
document as a coauthor by completing this form:<br>
<br>
<br>
<br>

<br>
<br>
<br>
There may be others that have expressed interest in this program<br>
<br>
or contributed through discussions outside of the dedicated
workshop<br>
<br>
series. Please feel free to forward this message to others<br>
<br>
and extend the invitation to sign as a member of the broader<br>
<br>
community that generated this document.<br>
<br>
<br>
<br>
We acknowledge that given the breadth of the program it is<br>
<br>
challenging for a committee to represent the individual
scientific<br>
<br>
interests of all members of the community with the same emphasis<br>
<br>
and detail as they would themselves. However, we are unified in<br>
<br>
our goal of pursuing world class science.<br>
<br>
<br>
<br>
The deadline to sign as an author is June 7 at close of<br>
<br>
business (5 p.m. EDT). We are planning to submit to the arXiv<br>
<br>
after deadline and submit for publication in a refereed journal.<br>
<br>
<br>
<br>
On behalf of the editorial committee,<br>
<br>
<br>
<br>
Patrizia Rossi<br>
