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.

Last Chance to Submit Nominations for the 2015 Outstanding Nuclear Physicist Award
The JSA Programs Committee established the Outstanding Nuclear Physicist Award in 2011 to recognize individuals who have made outstanding and sustained contributions, including technical achievements, to experimental and/or theoretical research related to the nuclear physics program at Jefferson Lab. The biennial award consists of a certificate and a $10,000 honorarium, presented to the honoree at the Jefferson Lab Annual Users Group meeting. Nomination packages are due by Feb. 2 and should be submitted electronically to with the subject line: "2015 JSA ONP Nomination." For detailed nomination instructions, visit the website.

Center for Theoretical and Computational Physics

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.
