1621st Century Science QuestionsWhat is the role of gluonic excitations in the spectroscopy of light mesons?

Where is the missing spin in the nucleon?Role of orbital angular momentum? Can we reveal a novel landscape of nucleon substructure through measurements of new multidimensional distribution functions?

Can we discover evidence for physicsbeyond the standard modelof particle physics?

Like to give an overview of Jefferson Lab. I cant get going without saying something of the current status of the lab.

The dominant part of the talk will concern our 12 GeV Upgrade Project, the physics and the project status.

A Laboratory for Nuclear Science

The Jefferson Lab electron accelerator is a unique world-leading facility for nuclear physics research and related applications

12 GeV Upgrade ensures at least a decade of excellent opportunities for discovery New vistas in QCD Growing program Beyond the Standard Model

EIC moving forward: Strong science case, much builds on JLab 12 GeV program MEIC design well developed time scale following 12 GeV program is natural
