12 GeV Upgrade
Everybody involved with the Hall C portion of the 12 GeV Upgrade Project rejoiced when the Department of Energy concurred that the Hall C Key Performance Parameter (KPP) had been demonstrated several weeks ago. Achievement of this milestone marked the conclusion of years of R&D, design, construction, installation and testing for the Hall C upgrade. The accelerator had delivered high-energy electrons for this KPP run, during which experimenters worked feverishly to collect and analyze data and report the results. Thanks to the intense installation work of the previous several months, Hall C was ready for beam delivery as planned. Timely completion of this objective was possible only due to the coordinated efforts of work groups from across the laboratory. Attention has now turned to preparation of the final project documentation and closing-out the earned-value-management and financial aspects of the Hall C 12 GeV Project. This material, documenting full Hall C scope completion, will be presented at the review to be conducted by DOE's Office of Project Assessment on May 10-11.

Center for Theoretical and Computational Physics
Recently, it has been demonstrated that light-front parton distribution functions and generalized parton distributions can be related to so-called quasi-distributions, which can be calculated nonperturbatively directly using lattice Quantum Chromodynamics, formulated in Euclidean spacetime. This relation is based on the basic assumption that the quasi-distributions obtained using Euclidean correlation functions coincide with those obtained from their Minkowski counterparts, which was recently brought into question. Now, new work has shown that quasi-distributions are indeed identical in Euclidean and Minkowski spacetimes.
