...and they're off!
See the start (and finish!) of this year's Run-A-Round on the Jefferson Lab Facebook page. Thanks to all the runners and volunteers for making this one of the most successful Run-A-Rounds yet! Run-A-Round photos to come!











EXPERIMENTAL NUCLEAR PHYSICS

Searching for A-Prime
After the completion of a series of experiments with the new CLAS12 spectrometer, Hall B is preparing for an experiment called Heavy Photon Search or HPS. This experiment searches for evidence of a hypothetical particle, called A', also known as A-prime, which is thought to connect the visible matter in the universe with the invisible or dark matter.

Most of our universe is made from dark matter, which we know from the deflection of visible light traveling in the universe through areas where dark matter is concentrated. Many experiments are searching for the A' particle, including an experiment in Hall A, called APEX. HPS is unique in the sense that it explores areas in parameter space where other experiments have no sensitivity. Finding significant evidence for the A' particle would revolutionize our understanding of the universe.
  

THEORY & COMPUTATIONAL PHYSICS

Interpretation of the LHCb Pc(4312)+ Signal
The LHCb collaboration has reported a new pentaquark-like signal, Pc(4312), in the experimental J/ψ p spectrum, near the threshold for the Σc baryon and D-bar meson. A new paper analyzes this spectrum by constructing an amplitude that respects the general principles of S-matrix theory. The Σc D-bar interaction is found to be attractive, but not sufficient to form a bound state.
 

ESH&Q

Celebrate National Fall Prevention Safety Stand-Down Day
Jefferson Lab will celebrate Occupational Safety and Health Administration’s 6th Annual National Fall Prevention Safety Stand-Down Day on Thursday, May 9, between 11:30 a.m. - 1:30 p.m. in the ESH&Q Building (Bldg. 52), Large Conference Room (Room 9). Activities will include inspections of fall protection gear including harnesses, lanyards and anchorage connecting devices such as beam clamps and straps. Want to know more about the use of fall protection at the lab? Staff will be on-hand to address your questions; and, while you're there, enjoy free pizza and soda! Questions? Contact George Perry at gperry at jlab.org or x7841.
  

  

COMPUTING

Jefferson Lab Software Changing
The IT Division has been working with Proofpoint, the previous Spam and Virus filter service provider, and plan to implement this new service in place of the Office 365 spam and virus filter on Tuesday, May 14. Jefferson Lab staff will be able to important allow and block lists from the previous Proofpoint. Staff and Users will receive spam quarantine Reports daily unless they modify their settings. With the implementation of Proofpoint, employees and Users can expect fewer messages to end up in their junk email folder. Questions or concerns? Please contact the IT Division Help Desk at helpdesk at jlab.org or x7155.

Employee Spotlight
Jefferson Lab employees might notice a new smiling face at the top of CEBAF Center in the B Wing. Alethea Ashton is the new the administrative assistant for the Director’s Office in CEBAF Center at Jefferson Lab. Although she’s served as a courtroom clerk in Charlotte for the last few years, her first foray at the lab was in the summer of ’98, when she worked in the equipment pool supplies department. What brought her back to our neck of the woods? “I loved the diversity at the lab. And I loved that no matter what your experience, you were always a part of the conversation. Everyone was willing to share what they were working on. I’m glad to be back.” Please welcome her at alethea at jlab.org or x5700.
 
    
   Alethea in 1998                                       Alethea today

Jefferson Lab Published Journal Articles
and Department of Energy Pages
Jefferson Lab must submit the final peer-reviewed accepted manuscript to DOE for the purpose of allowing these papers to be available through DOE's Public Access Gateway for Energy and Science. The lab is graded on its submissions of the copies which contain the same content as the final published version of journal articles, but without the copyrights and journal formatting. The only exception is for journal articles which are published Open Access, as the public can access these papers directly without a subscription or having to visit a library. Authors, when submitting your papers to journals, please keep this in mind and remember to retain such a copy to provide to the lab's STI manager Kim Edwards at kindrew at jlab.org or x7805.
