Center for Theoretical and Computational PhysicsThis week, members of the Jefferson Lab Theory Center and Experimental Physics Division joined users in a dedicated workshop on γZ box corrections to parity-violating electron scattering. The workshop saw significant progress made towards a consensus about the size of the γZ corrections to the Q-weak experiment and, particularly, their uncertainties. These corrections are vital for understanding whether the Q-weak experiment is to achieve its goal of measuring the fundamental weak mixing angle of the Standard Model, sin2ΘW, to an unprecedented high level of precision.

Facilities Management & LogisticsUnplug Those Holiday Decorations
Everyone is reminded to turn off and unplug all electrical decorations when they depart work each day or by 6 p.m. In addition, all decorating materials must be resistant to fire, and only UL-approved lighting/electronics may be used.
JLab Calendar of Events
Dec. 16-18: Hall A Collaboration Meeting
Environment, Safety, Health and QualityNotable Event Notice: Dec. 16 Failure to Comply with Posted Signs
On Dec. 16, a GERT-trained subcontractor moved a Radiation Control group Controlled Area sign that was hanging on a fixed ladder to gain access to the area located directly above the Vertical Test Area. The signage was attached to the ladder by a magenta and yellow bungee cord, but the contractor did not pay attention to verbiage on the sign.
This area had been posted on Friday, Dec. 13, as the Superconducting Radiofrequency (SRF) group was scheduled to begin testing a cavity with a 1 Watt amplifier over the weekend. The contractors performed a walk-through of the site on Friday; however, they failed to take a look at this particular area.
Signs are posted to communicate important safety information. Please read and obey posted signs. If you are ever confronted with a sign that you question or don't understand, call the phone number on the sign to seek clarification. If a phone number isn’t listed on the sign, call the office, work group or person responsible for the sign. If you still have unresolved questions or concerns, contact your division safety officer or the safety warden for the area where the sign is posted. For more information, see the All-Staff Memo.

Quark Cafe staff invites the Jefferson Lab community to its annual Holiday Bake Sale on Friday, Dec. 20, 10:30 a.m.–1:30 p.m. The bake sale will be in the CEBAF Center lobby and will include a variety of breads, holiday cakes and pies by Gerry Fortin, owner of Lucille's Bakery in Richmond. A price list can be found on the lab's We Hear That page.
Pressure Systems Awareness Training Offered
Pressure Systems Awareness Training, SAF130A, will be held Jan. 8 at 11 a.m. in CEBAF Center room F113. Registration is available through the Learning Management System. Additionally, Job Task Analysis (JTA) questions regarding pressure systems and safety hazards have been revised. In order for updates to reflect in your Skill Requirements List, your supervisor must go into the JTA and update the record. The updated questions are: Does this position require the operation, repair or design of a pressure or vacuum system? (SAF130A Pressure Systems Awareness); and Does the work involve stored energy or movement hazards (e.g. compressed gasses, magnets, robotics)? (MED01 Medical Monitoring for Hazardous Work, SAF104 Lock Tag and Try).
GEN034 Annual Security Awareness for Employees & Subcontractors
Each year, all employees and subcontractors are required to complete Annual Security Awareness training, GEN034. The GEN034 module is currently being revised and will remain unavailable until Jan. 2. Due to the delayed access to this module, the expiration date for the current period has been extended to Jan. 31. Training and Performance appreciates your patience as they work to update the training material. If you have any questions about training, contact Brandye Rogers, x5959, or Bruce Ullman, x7170.
