    1. 10. Summary EIC MC activities
      Markus Diefenthaler (Jefferson Lab)

      The EIUCG Software Working Group (SWG) is working on physics and detector simulations that enable a quantitative assessment of the measurement capabilities of the EIC detector(s) and their physics impact for the Yellow Report Initiative. The common simulation tools and workflow environment being set up by the working group allows the EICUG to pursue the Yellow Report studies in a manner that...

    2. 11. Second order Radiative corrections for ep Scattering
      Prof. Hubert Spiesberger (JGU Mainz)

      High-precision measurements of lepton nucleon scattering will require knowledge of higher-order radiative corrections.
      I’ll describe a calculation of QED leptonic corrections including contributions from 2-loop virtual corrections, 2-photon
      emission and 1-loop corrections for 1-photon radiation. A Monte Carlo simulation code was developed for elastic ep
      scattering.

    3. 12. Higher-order calculations of RC for ep and Moller scattering

      Proton radius puzzle is the discrepancy between inferred proton radius in ep scattering and in muonium spectral measurements. In a remarkable recent experiment, PRad, it was demonstrated that earlier results for $r_p$ in ep scattering must be reconsidered. The systematic error analysis for this experiment has shown that the dominant source of systematic error comes from radiative corrections....

    7. 16. Opportunities at EIC with Both Lepton Signs
      Richard Milner (MIT)

      EIC is motivated by the possibility to scatter electrons from hadrons. i.e. to utilize the well-determined QED interaction to understand how the quarks and gluons of QCD form the bound systems which account for the visible mass in the universe. The perturbative QED expansion is significantly affected both by radiative processes as well as higher-order terms which are believed to be...
