12 GeV Upgrade
The Physic Division held an equipment readiness review of the Super High Momentum Spectrometer Q1 magnet on Jan. 21. No major issues were identified and cooldown of the Q1 magnet will soon commence. The final 12 GeV Upgrade civil construction activity (tunnel air conditioning) is well underway. The related work in the tunnel involved drilling into the overhead to install hangers for the chill beams and associated piping. The subcontractor used a drilling tool for the overhead work. This apparatus allowed the subcontractor to apply an engineered solution to eliminate the ergonomic stresses to the workers, and the attached HEPA vacuum provided local capture ventilation for silica generated during the drilling. During the monthly progress meeting, the feedback from the subcontractor was that the tooling provided the added benefit of significantly increased efficiency for the task.

The decay of K -> ππ e νe has been measured with a high level of precision, first by E865 at Brookhaven National Lab and more recently by NA48/2 at CERN. This decay is of considerable interest as a window into the dynamics of the strong interaction at low energy. Previous treatments, relying on chiral perturbation theory alone, failed to accurately match the data. A new theoretical analysis of this process, using dispersive techniques, takes into account all the ππ- and Kπ- final state interactions and yields excellent agreement with the data.
