[Cuga] Registration Open for “Science at Mid x: Anti-Shadowing and the Role of the Sea” workshop- a message from Thia Keppel

[Lorelei Carlson]

Dear Colleagues,

We are pleased to invite you to join the upcoming “Science at Mid x: Anti-Shadowing and the Role of the Sea” workshop, a part of the 2022 series of summer workshops being organized jointly between the Jefferson Lab Users Organization (JLUO) and the laboratory to probe the science that would be facilitated by a higher energy electron beam (~22 GeV) at Jefferson Lab. See https://www.jlab.org/conference/hews22

An upgrade of CEBAF at Jefferson Lab beyond 20 GeV will open up key science that is not possible to access at 12 GeV. One kinematic regime where this is most possible is in the "middle" Bjorken x regime around x~0.1, where the available momentum transfers at 12 GeV have heretofore limited or prevented several exciting measurements. Here, for example, the long-standing mystery of anti-shadowing may now be probed for the first time in decades. The strange sea may now be measured with minimal theoretical bias using parity-violating electron scattering. More generally, the interplay of the valence and sea regimes may be better disentangled. Novel tagged measurements may provide access to meson structure and the role of mesons in nuclei. All of these measurements leverage the unique capabilities of luminosity and precision possible at Jefferson Lab in the EIC era. This workshop seeks to enhance our knowledge of these topics and broadly identify exciting new science opened up in this middle x regime via experiments that initially utilize largely existing or already-planned Hall equipment.

The workshop will take place on the mornings of July 22,23. Registration and agenda information are provided from the link at  https://indico.jlab.org/event/531/ Please register for the workshop if you plan on attending, and feel encouraged to contact the organizers if you have pertinent projections or ideas that you would like to be considered for presentation.
