[Clas12_first_exp] Abstract for the APS DNP

[sangbaek at jlab.org]

Dear Colleagues,

I will give a 30 minute talk at "QCD Towards the EIC", a workshop of the
2024 Fall Meeting of the APS DNP (https://web.mit.edu/dnp2024/index.html).
I wrote the abstract to fit the title of the workshop, but my talk will be
about the JLab experiments, mostly about CLAS12.
Please let me know if you have any comments. The deadline for submitting
the abstract is Monday 7/8. I will submit the final abstract to APS DNP
and upload it to the CSC db.

Session: QCD Towards the EIC (workshop for the 2024 Fall Meeting of APS DNP)

Title: 3D Imaging of Quarks and Gluons in the Nucleons and Nuclei.

Abstract:
In this talk, I will explore the three-dimensional imaging of quarks and
gluons within nucleons and nuclei in the Jefferson Lab (JLab) and the
Electron-Ion Collider (EIC). I will introduce the state-of-the-art 3D
tomography programs that enhance our understanding of the internal
structure of hadrons. The discussion will focus on the cross section
measurement of Deeply Virtual Compton Scattering off the proton with the
CLAS12 detector using a liquid hydrogen target and a 10.6 GeV CEBAF
electron beam in Hall B, JLab. The discussion will extend to a recently
proposed gluon distribution study in Hall B, involving the coherent
𝐽/𝜓 electroproduction off a He-4 target and the ALERT
recoil detector. Summarizing the lessons from the ongoing experiments, I
will discuss the design and impact of the future quark and gluon
distribution studies at EIC.
