A majority of approved physics experiments that will be running with 12-GeV electron beams at JLab require at least a per-cent accuracy in the measurements of differential cross sections and polarization asymmetries, making electromagnetic corrections crucial for interpretation of data.  Recent Jefferson Lab measurements of single-spin asymmetries from two-photon exchange (TPE) in DIS revealed the effect is at a per-cent level, making TPE a high-priority issue for SIDIS analysis of single-spin asymmetries, and will also be of concern for deep-exclusive processes. Extension and further development of the theoretical and computational approaches to higher-order QED effects for electron scattering is an outstanding problem for the upcoming physics analysis effort at JLab.

The workshop on "Precision Radiative Corrections for Next Generation Experiments" will address outstanding issues of QED radiative effects for several critical research areas including:

1. Studies of nucleon's Generalized Parton Distributions (GPDs) and Transverse Momentum Distributions (TMDs)
2. Measurements of the elastic form factors and resonance transition form factors of the nucleon
3. Effects of nuclear medium on the properties of hadrons
4. Search for physics beyond the Standard Model of electroweak interactions

Dedicated sessions will address items involving radiative corrections, including:

1. Structure Functions from models and phenomenology, needed as input for radiative correction calculations
2. Different MC programs using radiative effects
3. Integration of Radiative corrections into the extraction chain (in particular extraction of 3D PDFs from data)
4. TPE-induced electromagnetic effects and T-odd contributions

One  of the main goals of the  Workshop will be the development of a clear and specific plan for providing radiative corrections in the extraction of 3D PDFs, GPDs and form factors in nucleons and nuclei, thereby supporting the JLab12 physics program as well as the development of a strong physics case for the Electron Ion Collider.
