This workshop is organized to explore the complementary physics potential offered by a polarized positron beam at JLab. We seek presentations and discussions in the context of CEBAF 12 GeV operation, a possible Positron-Ion collider (complementary to an Electron-Ion Collider), and include the community interested in low-energy positron applications. Workshop proceedings are planned to inform a White Paper for a positron physics program at JLab.<br style="" data-mce-style=""><br style="" data-mce-style="">Workshop topics include:<br style="" data-mce-style="">-Multi-photon exchange<br style="" data-mce-style="">-Deeply virtual Compton scattering<br style="" data-mce-style="">-Electroweak structure of hadrons<br style="" data-mce-style="">-Heavy quark production<br style="" data-mce-style="">-Beyond the Standard Model physics<br style="" data-mce-style="">-Low energy polarized positron beam applications <br style="" data-mce-style="">-Polarized electron and positron sources<br style="" data-mce-style="">-Multi-turn accumulation and fast kickers<br style="" data-mce-style="">-Positron beams at CEBAF, JLEIC and LERF<br style="" data-mce-style=""><br style="" data-mce-style="">The program will be composed of both invited and contributed talks, and is steered by an International Advisory Committee.
