C2.00001: The 3-dimensional Structure of the Nucleon Invited Speaker: Alexey Prokudin In my talk I will review the current status of studies of 3D structure of the nucleon. I will pay special attention to recent developments in phenomenology of Transverse Momentum Dependent distributions. Current status of theory and phenomenology and prospects for future will be discussed. [Preview Abstract] |

C2.00002: Nucleon Tomography Invited Speaker: Latifa Elouadrhiri A fundamental challenge of modern nuclear physics is to understand the structure of the constituents of nuclear matter, protons and neutrons. The 12 GeV Upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab and the construction of state-of --the-art detector systems make it a unique facility in the world to address this challenge. Electron scattering is a superb experimental tool to study the internal structure of nucleons at differing distance scales, as the resolving power of the probe can be varied. The Generalized Parton Distributions (GPDs) provide the theoretical framework to interpret the experimental data.~ The CLAS12 detector and continuous wave electron beams of up to 12 GeV energy will enable a collaboration of users' community from all around the world to perform precise exclusive experiments in a large kinematical regime to effectively engage in nuclear imaging, revealing hidden aspects of its internal structure, and providing insight into quark confinement forces in the nucleon. I will review the landscape of both theory and experiments, and describe the new equipment with a focus on the approved science program for the CLAS12 detector, which will provide a unique capability to study 3D nucleon imaging.

C2.00003: The TMD Program at JLab Invited Speaker: Zhiwen Zhao The TMD Program at JLab As a part of the general nucleon imaging effort, there have been many efforts to access the transverse momentum dependent parton distributions (TMDs) by using the semi-inclusive deep inelastic scatterings (SIDIS) processes. the recently upgraded Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) provides golden opportunities to study them in valence quark region. The TMDs describe the three-dimensional, spin-correlated densities of quarks and gluons in the nucleon in momentum space. The corresponding SIDIS measurement requires high intensity and polarization with large kinematic coverage which will be provided by several different detectors. In this talk, I will review the existing SIDIS results from the 6 GeV era and present an overview of the planned JLab SIDIS program at 11 GeV beam energy. [Preview Abstract] |

C2.00004: GPD and TMD measurements at the EIC: Mapping the position and motion of quarks and gluons in nuclear matter Invited Speaker: Markus Diefenthaler The Electron-Ion Collider (EIC) is envisioned as the next-generation U.S. facility to study quarks and gluons in strongly interacting matter. The broad physics program of the EIC aims to precisely image quarks and gluons in nucleons and nuclei and to reveal the origin of the nucleon spin by colliding polarized electrons with polarized protons, polarized light ions, and heavy nuclei at high luminosity. In my presentation, I will discuss why the EIC is not only the next natural step for our field but also why it has the potential to revolutionize nuclear physics. I will focus on the study of generalized parton distributions (GPDs) and transverse-momentum distributions (TMDs) which allow to map the position and motion of quarks and gluons in nuclear matter.
