Physics opportunities with the 12 GeV upgrade at Jefferson Lab

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

Boosted Multijet Resonances and New Color-Flow Variables

We use modern jet-substructure techniques to propose LHC searches for multijet-resonance signals without leptons or missing energy. We focus on three-jet resonances produced by
