abstract
This white paper summarizes the scientific opportunities for utilization of the upgraded 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF) and associated experimental equipment at Jefferson Lab. It is based on the 52 proposals recommended for approval by the Jefferson Lab Program Advisory Committee.The upgraded facility will enable a new experimental program with substantial discovery potential to address important topics in nuclear, hadronic, and electroweak physics.

World data on isoscalar DIS cross-section ratios exhibit near-perfect cancellation of nuclear effects in the valence region 0.25 ≤ x ≤ 0.35 across nuclei.
Short-range correlated pairs account for roughly 20% of nucleons in any nucleus and nearly all high-momentum nucleons, originating from the nucleon-nucleon tensor force.
The notes provide an introduction to transverse momentum dependent distributions and their use in imaging hadrons, complementing lectures at several graduate schools.
