12 GeV Upgrade
Conventional Facilities scope is 99.7 percent complete. On the Tunnel Air Conditioning project, the final closeout items include completion of remaining punchlist items outside of the tunnel, submission of project documentation (such as commissioning report and as-built drawings), connection of water meters to electronic central system, and final payment. On the Backup Cooling Towers at the North and South Access Buildings, the final project closeout items are the as-built drawings.

Center for Theoretical and Computational Physics
A new paper on the pion form factor in the covariant spectator theory produced the unexpected result that new contributions, required by charge conjugation symmetry, were large but did not alter the shape of the form factor. Therefore, after normalizing the form factor, the new results are essentially identical to the original calculation, giving a prediction that agrees with the data for large pion masses (around 400 MeV) but has the wrong shape for physical pion masses. The next step is to calculate the missing contributions coming from dressing the quark current and the pion wave functions to higher orders.
