12 GeV Upgrade
Hall B and Hall C saw increased work activities in preparation for the demonstration of each Key Performance Parameter for the 12 GeV Upgrade Project and commissioning runs scheduled for this spring. Hall B completed the installation of the Central Time of Flight and High-Threshold Cherenkov Counter detectors. Work continues on the instrumentation/controls and gas systems needed to support detector operations. Hall C saw progress in both the Dipole and Q3 magnet installations and commissioning. Significant items of note were the completion of the pressure and leak testing of the liquid nitrogen and helium circuits for the Q3 magnet; both systems passed.

Center for Theoretical and Computational Physics
Sum rules for light-by-light scattering provide a basis for calculations of key contributions to the muon's anomalous magnetic moment, which is important for upcoming experiments at Fermilab and J-PARC. The simplest of such sum rules is tested with currently available data on two-photon collisions in this new paper. This is shown only to be satisfied if the measured large four pion production cross section is dominated by its helicity-two component.
