Dear Colleagues,
<br>
<br>
We would like to bring your attention on the newly created Positron
Working
<br>
Group (PWG) at Jefferson Lab. In support of a growing interest,
this working
<br>
group has been formed to explore the physics possibilities with
respect to a
<br>
positron experimental program at JLab. This next step is to frame a
strategy
<br>
that successfully motivates positron beams at 12 GeV CEBAF, a
future
<br>
Electron-Ion Collider or the LERF.
<br>
<br>
The PWG is organized into five topical sub-groups:
<br>
<br>
• Interference Physics (John Arrington and Charles Hyde);
<br>
• Charged Current Physics (Yulia Furletova and Wally
Melnitchouk);
<br>
• Tests of the Standard Model (Marco Battaglieri and Xiaochao
Zheng);
<br>
• Positron Applications (Tony Forest and Farida Selim);
<br>
• Positron Production and Beam Physics (Joe Grames and Vasiliy
Morozov).
<br>
<br>
The inaugural goal of the PWG is to investigate the capabilities,
<br>
requirements, and physics reach with respect to each of these
topics and
<br>
then deliver a Jefferson Lab Positron Physics White Paper in 2017.
<br>
<br>
We encourage your participation in this process. The first step is
to
<br>
subscribe to the PWG mailing list at <a
class="moz-txt-link-abbreviated" href="mailto:pwg@jlab.org">pwg@jlab.org</a>
(please indicate
<br>
“subscribe” as the e-mail subject) or by visiting the PWG home page
<br>
<a class="moz-txt-link-freetext" href="https://wiki.jlab.org/pwg">https://wiki.jlab.org/pwg</a>.
You may also directly contact the PWG
<br>
coordinators.
<br>
<br>
Best regards,
<br>
<br>
Eric Voutier & Joe Grames for the PWG
