Center for Theoretical and Computational Physics

A new paper <arXiv:1505.01715> presents a unitary dispersive model for η→3π meson decay into three pions, based upon the Khuri-Treiman equations. The approach incorporates substraction constants fixed by fitting recent high-statistics η→π+π-π0 data from WASA-at-COSY.  Based on the parameters obtained and matching to chiral perturbation theory, the slope parameter for the neutral channel and the quark mass double ratio are predicted to be α=-0.022±0.004 and Q=21.4±0.4, respectively.

Lab-wide Annual Property Inventory Underway, June 1 – July 31
Jefferson Lab’s annual property inventory started on June 1 and will run through July 31. The property manager has randomly selected 20 percent of the lab's property custodians for this year's property inventory. Those custodians will be contacted by a member of the property staff. (Custodians that did not complete their annual property validation will also be included in the inventory group.)
To complete the inventory, each item must be physically seen by a member of the property office. Note that the property custodian is responsible to know and search if needed for their assigned property, not the property staff.  Property staff will go to the location identified for each item during the property validation to inventory the property. The assigned custodian will be notified of any item not located at its specified location, and the item will be reported as "missing" until the item is physically located by the custodian and verified by property staff. 
If you have questions regarding property validation or the inventory, contact Christian Whalen at x5899 or ctwhalen@jlab.org.  For questions regarding key validations, contact Dennis Merritt at x7963 or merritt@jlab.org.

Fire Hydrant Testing Around CEBAF Center after 4 p.m. on June 4
Fire hydrant flow testing will be performed for CEBAF Center on Thursday, June 4, after 4 p.m.  The duration of the test will be no more than 5 minutes. It shouldn’t impact any activities or work in CEBAF Center or the rest of the campus. Water will run across the parking lot and into storm drains. Anyone with specific questions may contact Dave Kausch, Facilities Maintenance and Logistics, at kausch@jlab.org.

Environment, Safety, Health and Quality

Interns, Program Participants are Arriving Daily: Help Them Work Safely
This year Jefferson Lab is fortunate to have approximately 300 students/interns: high school, undergraduate and graduate students, and post doctorate workers with us for several months. With this influx of a large number of new people who are not familiar with JLab's physical layout nor its policies and practices, the potential for an injury or adverse event can be very high. This is offset by connecting the student to a JLab staff member who determines the necessary preparation for the student and provides a measure of oversight according to the type of student and workplace hazard.
Every student at JLab has a Sponsor; the Sponsor makes it possible for the student to have a JLab computer account. The Sponsor may also act as the Mentor/Supervisor. Sponsor and Mentor/Supervisor are very specific terms at JLab. If you are going to be a Mentor/Supervisor, take the on-line training designated MGT202 JLab Mentoring Program, which is accessible from the web-based training webpage.

The Sponsor may also request that another JLab employee serve as a Mentor/Supervisor for the student. The Mentor/Supervisor ensures that the student is prepared for work - has the appropriate training - and provides oversight for the student’s activities. (Oversight means sufficient presence at the student's work site to ensure that the student remains within the defined scope and work and follows safety requirements.)
Whether we are a Sponsor or have a Mentoring/Supervisor relationship with one of these new arrivals, or if we encounter them in the normal course of work, we should be sure they know how to function safely.  We can do this by observing their work and asking a few questions related to their work: Have they been given an orientation for their workplace, have they been prepared for the job at hand (understand the scope of work, been trained, read procedures and related Task-List entries, and know who their Mentor/Supervisor is)?
We all know that JLab can be daunting to new arrivals, so, if you observe an unsafe act or what appears to be improper workplace behavior by a student, take a few extra minutes to help the student understand how to work properly and safely.

Announcements

Know, Heed the Jefferson Lab Smoking Policy
A number of complaints have been received from Lab staff that individuals have been smoking in buildings or just outside the doors of buildings. As a reminder, smoking (this includes both traditional smoking products and vapor/electric cigarettes) is not permitted:
·  Inside any building or
·  Within 50 feet of entrances, operable windows, or outdoor air intakes except in smoking shelters that have been placed around the Lab or
·  In any government owned vehicle, cart, or equipment assigned to JSA/JLab, either on or off the Laboratory grounds.
The Lab’s Smoking Policy, published in Section 208.07 of the Jefferson Lab Administrative Manual was updated in 2014.
The policy applies to all JSA/Jefferson Lab staff, users, students, subcontractors, visitors and guests.
Cigarette butts and other smoking debris should not be thrown on the ground. Cigarette receptacles are available in the smoking shelters and should be used for cigarette disposal.
Managers and supervisors are responsible for implementing this policy in their work areas.  Please ensure all staff, users and visitors are aware of and in compliance with this policy.
Read the entire policy online at: https://mis.jlab.org/mis/apps/portal/admin_manual/viewDocument.cfm?documentId=77198

Firefighters at Lab on June 5 for Training Program; Expect Congestion in CC Parking Lot, Front Atrium
Nearly 100 Newport News Firefighters will be at Jefferson Lab on Friday, June 5 from 8 a.m. - 5 p.m. for a training program. Expect congestion in the main CEBAF Center parking lot. To avoid congestion, you may want to park in the lot between CEBAF Center and the Support Service Center (SSC) or in the lot behind the EEL, Bldg. 90. They will be eating offsite, so there shouldn't be much of an impact on the cafeteria. 
Also, first thing in the morning, all participants will be signing the visitor’s log at or near the CEBAF Center reception desk. There may be congestion at or near the reception desk, front atrium and C Wing first-floor restrooms first thing in the morning. The group will be in the CEBAF Center Auditorium and lobby areas.

JLab Implements Process to Improve Public Access to Research Results
In October 2014, the Department of Energy began implementing its Public Access Plan across the DOE complex. This requirement stems from a Feb. 22, 2013 memorandum titled, "Increasing Access to the Results of Federally Funded Scientific Research," in which John Holdren, director of the White House Office of Science and Technology Policy (OSTP), directed federal agencies to develop and implement plans for increasing public access to the full-text versions of final, peer-reviewed publications and digital research data resulting from agency funded research.
Public Access, or Open-Access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions to readers, according to Kim Edwards, Jefferson Lab’s publications manager. All authors of lab research results are asked to follow this process, which is posted online at: https://www.jlab.org/memo/jlab-implements-process-improve-public-access-research-results

JLab to Test Tornado Warning Siren at 10:30 a.m. on Friday, June 5
Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, June 5.  Depending on weather conditions at the time of the test, the siren may be heard by anyone within a 1.5-mile radius of the lab.
Don't respond to the siren; this is a test of the siren system and not a personnel response exercise.
The test shouldn't last more than three-minutes. Jefferson Lab uses the siren to notify members of the lab community, who are outdoors, to Take Cover in the event of a tornado or tornado warning. Individuals planning to be in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection.
Jefferson Lab’s Site-Wide Alert (SWA) system (email, page, and Cisco phone text messages) will be used to remind the lab community of the test in the hour before the siren is sounded. If this test were an actual Tornado Warning, the SWA system messages and siren would direct you to take cover immediately in a Severe Wind Take Cover area.

JLab Weekly Briefs is an ongoing publication providing information on the status of safety, accelerator operations, experiments, free-electron laser, reviews, upcoming activities and special events. Deadline for submission is every Tuesday by 10 a.m. Submit new items to: Public Affairs or contact Kandice Carter at x7263.
