International Workshop on Physics with Positrons at Jefferson Lab
September 12-15, 2017
Thomas Jefferson National Accelerator Facility
Newport News, VA

Second Circular

Registration for the Workshop on Physics with Positrons at Jefferson Lab is now open.

Abstract Submission deadline is extended to September 1, 2017.

We are now only accepting abstracts for invited oral or contributed poster presentations.

This workshop is organized to explore the complementary physics potential offered by a polarized positron beam at JLab.  We seek presentations and discussions of the application of positron beams in the context of CEBAF 12 GeV, a possible Positron-Ion collider (complementary to an Electron-Ion Collider), and an eventual low-energy positron facility.

The physics potential will be evaluated on the basis of beam intensity and polarization. At CEBAF 12 GeV, beam intensities about 10-100 nA CW and >60% polarization are expected, at EIC energies a luminosity of 10^33 cm-2/s and >40% polarization are considered and at low energies positron beams with a flux about 10^10 e+/s with >50% polarization are likely. Workshop proceedings are intended to inform a White Paper for a positron physics program at JLab.

The workshop is organized in plenary and parallel sessions according to the topics:

- Interference physics (J. Arrington & C. Hyde, conveners)
- Charged current physics (Y. Furletova & W. Melnitchouk, conveners)
- Test of the Standard Model (M. Battaglieri & X. Zheng, conveners)
- Positron applications (T. Forest & F. Selim & B. Vlahovic, conveners)
- Positron source and beam physics (J. Grames & V. Morozov, conveners)

The program will be composed of both invited and contributed talks, and will comprise also a poster session. Student support is available to encourage their participation in the workshop.

Registration Announcement

Registration is now open.


This 4 day workshop plans to explore the scientific basis for polarized and unpolarized positron beams at JLab in the context of 12 GeV CEBAF, the proposed Jefferson Lab Electron Ion Collider (JLEIC), and also for low energy applications. An accelerator session dedicated to positron production and beam formation for each scenario completes the scientific program.   Collecting the motivation and requirements for a positron physics experimental program within the workshop proceedings as a basis for a Jefferson Lab Positron Physics white paper is a key goal of the meeting.  The workshop will cover the following topics:

  • Multi-photon exchange
  • Deeply virtual Compton scattering
  • Electroweak structure of hadrons
  • Heavy quark production
  • Beyond the Standard Model physics
  • Low energy polarized positron beam applications
  • Polarized electron and positron sources
  • Multi-turn accumulation and fast kickers
  • Positron beams at CEBAF, JLEIC and LERF

The workshop agenda will be composed of plenary sessions with both invited talks steered by an international organizing committee and contributed talks.  A reception and networking/poster session are also planned.  Students are especially encouraged to contribute to the workshop poster session.  Those interested in presenting at the workshop are encouraged to contact the organizing committee

The workshop is jointly supported by Jefferson Lab, Jefferson Science Associates and IPN Orsay.
