The dark photon, a weakly coupled light gauge boson motivated by astrophysical puzzles and as a solution to the muon "g-2" discrepancy, is the focus of future direct search experiments at Jefferson Lab. As the allowed dark photon mass, coupling and decay modes become more constrained by ongoing experiments, some predictions of that scenario are sharpened. A new paper shows that the new gauge boson can cause a shift in the weak mixing angle at the low Q2 by amounts potentially observable in the Q-weak experiment (currently under analysis) or future high-precision polarized Moller scattering measurements.

Loss of Control of Radioactive Material
Over the course of the shutdown, the inventory of items that are logged, tracked and stored as RAM increased significantly. These materials are easy to recognize by their bright yellow and magenta tags reading "Caution Radioactive Material." These tags are not to be removed except by RadCon personnel. In addition, workers must always notify RadCon to disassemble or relocate such items.
Materials that have been checked and cleared as non-radioactive, but are still located in the beam enclosure or are too large to be removed by RadCon, will have a white tag and wording indicating that the item is okay to move. Radioactive material tags and postings are an administrative control that helps prevent the loss or mishandling of RAM. Administrative controls are an essential element of safety and must not be neglected or subordinated to urgent work.
RadCon is working with Division Safety Officers and others to improve awareness in work areas with RAM storage. RadCon has also put together a short informational video to remind workers of the basic considerations for controlling RAM. This video may be viewed individually and in Toolbox meetings, and it is posted along with more information on the RadCon Operations home page. If you have any questions or concerns about radioactive materials, contact David Hamlette, 876-1743.
