12 GeV Upgrade
At the request of DOE's Office of Nuclear Physics, Stephen Meador, Director of the Office of Project Assessment in DOE's Office of Science, convened a team of 10 experts and eight observers for a Status Review of the 12 GeV CEBAF Upgrade Project at Jefferson Lab, held Oct. 25-26. The purpose of the review was to assess all ongoing aspects of the project, including technical, cost, schedule, management, and environment, safety and health. The review team provided valuable feedback in all areas, with a total of six recommendations in the closeout report. The committee enthusiastically congratulated all team members working in support of the 12 GeV Upgrade on the significant amount of work completed since a similar review last October and was supportive of the team’s planned approach to completing the project on schedule and cost.
Hall A has completed a planned, dedicated run for the GMp (proton magnetic form factor) experiment. Electromagnetic form factors describe the distributions of electric charge and current inside the nucleon and thus are intimately related to its internal structure. Hall A has now reconfigured to continue running with DVCS (Deeply Virtual Compton Scattering) as the primary experiment through to the winter break. DVCS will provide unique access to the three-dimensional structure of the proton through the generalized parton distribution framework.

Center for Theoretical and Computational Physics
A new Theory Center paper presents an exact solution to the Landau-Khalatnikov-Fradkin transformation for massive fermion propagators in momentum space in Quantum Electrodynamics by introducing a spectral representation. With this solution, the conditions required to ensure the gauge covariance of propagators have been deduced as constraints on the truncation of the Schwinger-Dyson equations. Such covariance requirements are essential to claims that the correct electromagnetic form factors of the pion and proton have been deduced from bound state calculations inputing such propagators.

Change Your Clock and Install New Batteries in Home Safety Devices
The end of Daylight Saving Time, which is set for Sunday, Nov. 6, is a good time to put new batteries in home carbon monoxide detectors, smoke alarms and other battery-driven safety devices, and it's a good time to test that these devices are in good working order.
